Eclipse 4.2 GUI is very slow [message #894739]

Tue, 10 July 2012 06:29

Eclipse User

Hello,

i'm using Eclipse 4.2 on Windows 7 64Bit with Java 1.7u5 64Bit and I think AND see that the GUI takes a long time to refresh themselves. It takes to long before a file gets opened in the editor. Thats not only on the JDT editor its on every view/editor!

I have tried to use the other themes but nothing changed...the GUI is very sluggish!

I know some performance problems occurs if you have a lot of plugins installed but i have tested it with the same plugins on Eclipse 3.8 and i cant determine this GUI-slownes there.

Is it possible to activate a native look&feel like in Eclipse 3.8 ?

Thanks!

I totally second that. My initial happiness regarding the visually attractive GUI completely vanished after realizing how everything takes 2-4 times longer, even simple things like opening a Tab...

What's your operating system? I'm on Mac and Windows and though 4.x is a
bit slower than 3.x I don't really notice this. From a performance PoV
the classic theme should perform best because it doesn't has to draw
shadows, ... .

Also disabling animations in the appearance preferences helps.

Oh man, I can't agree more! I was just switching between editor tabs and it was like 2-3 seconds delay between switches. On Win7 64 bit. Also the maven plugin especially seems reallllllly slow. Editing pom files and switching back and forth was an exercise in frustration.

Thanks Thomas for this "hidden" tip with the shadows. Smile

I have add or edit "swt-shadow-visible: false;" to all CSS statemants at "e4_basestyle.css" and "e4_default_win7.css" found at "\plugins\org.eclipse.platform_4.2.0.v201206081400\css" but improvements are not really noticeable...a little bit but not really.
Also animations were already disabled all the time.

BTW: Sorry for my poor english I speak primarily german and i hope you guys understand what I write here.

Changing the Appearance into "Classic" (Preferences->General->Appearance) seems indeed to speed up Eclipse again. I still find it strange how the new theme can slow down the UI so much... Now it's back to the old (ugly) style Sad

I noticed it too. My Juno got faster when I added this to my eclipse.ini file:

-vmargs
-Xms512m
-Xmx1024m

Maybe this vm thing is why I couldn't understand people complaining about performance.

First thing I do with any eclipse install is tune the vm. Having become a habit I thought people would tune the vm by default. I mean the default has 512 Megs.
One might think "Oh well in Indigo it wasn't needed." Well I guess it's like pc games: Games advance, and so should your graphics card Smile

I give 2 gigs on a 3 gig ram and don't find it noticeably slow.

It is always needed if you have a bunch of plugins installed! As in my case. Wink

I always tune the eclipse.ini a little with additional parameters. Doing that since I'm using eclipse (since Version 3.3).

--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile
-vm
D:/installed/Java/JDK_1.7.5_64bit/bin/javaw.exe
-vmargs
-Declipse.p2.unsignedPolicy=allow
-Xss4m
-XX:+UnlockExperimentalVMOptions
-Xms1024m
-Xmx2560m
-Dsun.lang.ClassLoader.allowArraySyntax=true

The VM is on a separate HDD as my Eclipse installation.

There are more parameters available and i tried to use them but there are some plugins they have problems with different parameters so I use only those that are really necessary.

But I also think an IDE should be as performant as possible. An IDE ist not a "Game", i really don't need an "eye orgasm" if i open up eclipse.
I need performance like a native UI as in previous versions.

Please, do not get me wrong.
The possibility of customizing via CSS is really amazing but you should have a choice between CSS styling and a native UI.

Thanks.

best regards...

Hi Rico. I guess we agree on the tuning then.

The game analogy was not to show that eclipse ide is a game, or eye orgasmic. It meant to show that when a software advances it may need more resources to be exploited effectively, just as Skyrim forced me to get a 1gb nVidia card some time ago. Hope you got my idea.

Also I think there's a bug somewhere tracking the providing of an ability to switch to native. I'll see if I can find it.

unfortunately I'm gree, Juno is very slow and the bad question is that all the world waited so long this version Crying or Very Sad

I believe that with this version, it is the first time that I would like to come back to an older version o to another IDE

Dear guys, I'm sorry but this is a real software failure...said by eclipse lover and fan

Ubuntu latest release, 4 GB ram, now use classic theme and start Eclipse with 512/1024 vmargs.
My coworkers using windows 64bit state same things...

Well, on which OS, with which theme?

Yes we are slower in some areas but frankly on my Mac and Windows
(inside VMWare) I can't hardly feel a difference.

What really drives me nuts though is that the MRU feature of tabs is
gone but I can't complain because I could have taken the time to
implement it.

So we need more information what is slow that we can fix it - and we
definately want to fix it.

As a final note: All and everything you can run in Juno 4.2 can be
installed in 3.8 [1] as well. There are no preconfigured distros but you
can simply use the update-manager.

Don't forget the -server option. I'm mostly using:

-vmargs
-server
-Xms128m
-Xmx768m

I really can't notice any annoying performance degree with v4.2. It feels
really good to me (Win7/x64)!

What is -server option? Could you explain it please, I wasn't able to find it

As I stated, I'm using Ubuntu and it is frustrating switch for example between an xml opened with xml editor and .java opened with java editor, I'm talking about a 50 lines of xml... at least 2/3 seconds to switch...
Layouting views and editor is impossible and very very slow, those green (ugly) lines don't appear when I'm dragging my view or editor to layout them...
Ant view sometimes looses its configuration files and I have to drag them inside view one more time

My coworkers using windows 7 64bit say that using the Windows 7 theme is impossible because of slowness and so all of them switched to Windows 7 classic theme.
I changed my theme too from GTK to classic

I'm talking about computers having good hardware, ram 4GB and modern processors.

Best regards and I hope noone is really thinking that IDE is like game...

If you are indirectly referring to my analogy regarding games I really don't see how difficult it is to understand what I really meant. Anyway, if you really think that I think that an IDE is a game then I again tell you that you are way off the truth.

The -server option is an argument given to the JVM while it starts. -server tells the jvm to optimize the overall runtime of the app meanwhile -client tells it to optimize starting time. Generally it is server by default (especially on 64 bit JVMs). You can see how you are running if you do java -version on command line:
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

While the additional ram helped a bit, it still remains noticeable slower than previous versions. And yes, exactly that switching between tabs of xml (e.g. poms) and java files are very annoying. And yeah, I am also talking of Quad 2.5Ghz+ with 4gig ram.

That said, it's not that previous Eclipse versions were Speedy Gonzalez anyways. Imo the reason lies in the SWT toolkit which is basically a tortoise anyways. People always tried to convince me how fast and performant SWT was compared to e.g. Swing, but I never experienced it that way. I really don't know where people got that illusion. I'd probably need to check out Netbeans if I have time.

Besides, I agree an IDE is not a game which needs to be colorful and sparkle, but the new theme gave me at least something nice and clean to look at compared to the previous versions.

Guess I gotta live with it. It's not that I expect performance to be increased magically...

Just to make sure I understand.

Is it slow:
a) when switching only between Java-Files
b) when switching between XML and Java-Files

If a) is fast and b) is slow this would indicate that the bottleneck is
e.g. the updating of the toolbar, ... .

About point "a":
Switching between Java-Files is faster than switching between Java & XML
Files AND switching between Java-Files is even faster with closed
Outline-View (not just minimized, completely closed!).
With closed Outline-View it is really significant.

About point "b": Right. I can confirm that.

I'm running also on a Core2Quad @ 2,7 GHz with 6GB of RAM and a
8800GTS-320 Nvidia Videocard.

I have been using eclipse to write c code for about 6 months and just switched from indigo to juno. I have never used eclipse to edit an XML or java file. That said...

c) GUI response is slow in juno when switching among .cpp files
AND
d) GUI response is slow in juno when opening and closing various Eclipse dialogs (e.g. "Open Resource")

It seems the GUI is just generally slow all around. The following changes made it run a little faster though, but it remains just slow enough to annoy a "power user" who spends 40 hours of week using Eclipse to write code:
- change theme to "classic"
- disable "animations"
- switch from icedtea jdk to oracle 1.7 jdk
- Xms512m & Xmx1024m (whatever that means)

Thank you!

Did you tried the 3.8 stream? There are no prepackaged distros put you
can you can simply use the update-manager to install CDT.

Hi.

I am new to eclipse. Eclipse also appeared to me very, very slow when switching between 2 tabs.

When I installed eclipse I copied it into c:\program files\eclipse

I think here is the problem.

I have moved eclipse to c:\eclipse\ and now it runs like a rocket.

Don't know. Maybe windows performs extra checks in those program files folders.

I can confirm that Juno becomes a way slower than Indigo. I'm using Eclipse for about 4 years and up to Indigo (3.7) it had very good performance on Windows (XP, 32bit, Classic theme), but on Fedora with KDE it was a bit slower (SWT uses GTK which seems slower anyway) however not very noticeable. But Juno (4.2) with Classic theme selected is a pain, because, for example, opening about 30 Java editors and doing Close All takes around 15 seconds on Athlon II 250 @ 3.2GHz with 8 Gb RAM while freezing GUI completely.

This one I can't confirm at least on an Ubuntu (inside a VM) even with
the new theme this is not taking more then say 2-3 seconds which
although still to slow is not that bad.

I am seeing the same type of problems as Maksym Kit. I have upgraded to Juno on a Windows XP platform. I installed the Eclipse Classic 4.2 Windows 32bit package. I have changed the theme to Windows 7 Classic. For a little info about my workspace, I have about 30 plug-ins and a target platform of the WTP project. I will be switching to 3.8 if this problem annoys me enough, but as a full time Eclipse committer on the WTP Dali project, I clearly have a vested interest in the future of e4!

I opened 20 java files in a Java perspective and it took 60 seconds! Choosing 'Close All' took about 20 seconds. Restarting Eclipse made it take closer to 15 seconds to open 20 java files.

I have attached a jvisualvm snapshot where I opened 30 java files in an empty Java perspective. I also attached a snapshot of closing those same 30 java files. It's hard to know exactly how to narrow the scope in jvisualvm. I have settings:

Start profiling from classes:
org.eclipse.e4.**

Profile only classes:
org.eclipse.ui.*
org.eclipse.e4.*
org.eclipse.core.*

Took a guess based on what I saw in a threaddump. If you need me to profile again with different settings, I am more than happy to do that. I will also let you know if I can reproduce opening 20 files taking 60+ seconds on the UI thread.

Thanks,
Karen

If you describe what is not working and file a bug we can fix it. You
don't specify what your OS is for example. I'm not having any trouble

I agree that 4.x is a bit slower than 3.x but not really noticeable. To me, double-click to maximize editor (i.e. Java Editor) is sometimes about 1 sec slower than 3.x

Hello guys,

Win7 x64

Work as is shoud

C:\eclipse4\eclipse.exe -data c:\_e4wsjre620 -vm "C:\Program Files\Java\jre1.6.0_20\bin\javaw.exe" -vmargs -Xms1024m -Xmx2048m -XX:MaxPermSize=1024m

damn slow, exactly as described here

C:\eclipse4\eclipse.exe -data c:\_e4wsjre7 -vm "C:\Program Files\Java\jre7\bin\javaw.exe" -vmargs -Xms1024m -Xmx2048m -XX:MaxPermSize=1024m

And with jre7 something is going wrong with the ftp support (remote system, aptana remote, iam sure other ftp-services also), no connection can etablished.

Maybe this can help to get e4 work till a generally solution is available.

adios, Stefan

Sorry Stefan, but do you mean that you notice slowdowns when using Java 6, but no slowdowns with Java 7?

No Brian, using Java 7 for whatever reason slows down the UI. After switching back to Java 6 my Eclipse installation runs in usual speed. Thank you Stefan great information!

@sopot: I'm running Eclipse 4.2 on a Win7 64bit machine. I noticed the bad UI performance when using Java 7u5 (64 bit). When using Java 6 or Java 7u7, both 64bit versions, everything works fine.

The u5 was released 5 days after Juno so it is possible most people have tried Juno with 7u5. I'm on same as you with 7u0 and don't notice any major slowdown.
There have been reports about slowdowns with java 6 also but anyway the biggest the feedback the more faster this thing is solved.

Have you read this jaxenter.com/eclipse-4-2-performance-slated-will-the-community-come-out-in-force-44390.html?
It is a sort of confirm of what we are stating in this thread, it's soon to speak about bugs and slowness, it's time to work hard to get a usable stable new release and then we could continue to send feedback

Go Eclipse dev team and good luck!

Thanks for taking the time to appreciate the committer's work. Keep in mind that most major performance upgrades are already fixed and are targeted for 4.2.2. Those that made it in 4.2.1 are just the initial ones.

I also had the problem of eclipse 'hanging' 2-5 seconds when just switching tabs. I attached JProfiler to Eclipse, and found most of the CPU time was spent in a plugin (Old Chronon plugin in my case). Uninstalled the plugin, and now it's much better.

What are those "most major performance upgrades" if you don't mind sharing?

Great to hear that there has been a major focus in perf improvement for 4.2.2, kudos to the Eclipse team! ... as none of this comes without a cost, resource wise ..

It's a bit of a pain to gather all performance related bugs (ESP on a Friday afternoon) but I'll put here some references to what I think are relevant. Note that there are much more open and the focus on 4.2.2 has been almost entirely shifted on performance so they are all being addressed.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=389335
https://bugs.eclipse.org/bugs/show_bug.cgi?id=391138

Also if you want to dig deeper this page http://wiki.eclipse.org/Platform_UI/Juno_Performance_Investigation shows the status, current actions and future plan for the fixes. At the bottom of the page you will find bugzilla queries for specific releases which will link you with a chain of related bugs.

I have this problem when editing XML files. Other files like .java work fine. I need to switch back to older Eclipse version to edit XML files. The problem is that the whole Eclipse UI hangs for several seconds when switching between XML files.

There is a feature patch for 4.2.1 which brings all performance
improvements to you and the XML one is one of them.

I just reimaged my machine with Fedora and was so pissed off on how Gnome screwed up the desktop, trying to find some comfort I thought I would do some coding. I saw that Eclipse 4 was out, knowing Eclipse had always done a pretty good job with releases in the past I decided to download it. When I started it I could not believe what I saw and felt, performance was horrible (I have a quad core Machine with 16G RAM), I could not do my usual customizations, the UI kept changing making it difficult to so what I needed to do. My solution? I downloaded Eclipse 3.7.2 and I was happy again.

You should download one of the latest builds towards 4.2.2 it has solved
most of the performance problems. Also make sure that you switch the
Eclipse Theme to the classic one.

Downloading and installing an Eclipse 3.8 works equally well (if not
better).

I found performance of 4.2.2 to be still below the acceptable level,
although not quite as bad as 4.2.0

Hi,

So what is still too slow to work with? Are the problems in 4.2.2 still
the same you have in 4.2.0/1, are there now different areas that are
still too slower?

Having used eclipse for several years on both Windows XP and Windows 7 with good performance. I recently switched to Linux (OpenSuse 12.2 KDE 4.9.4). The performance under Linux was terrible. Switching between editors, perspectives, views was a pain.

After searching the web I ended up with a tweaked eclipse.ini file. Now eclipse is running adequate. At least as good as it did in Windows. However I wouldn't mind some improvements though on its performance.

My laptop is running:
CPU: Intel Core i5-2450M 2,50GHz
Memory: 8GB
Graphics: Intel 4000
Harddrive: Kingston 480GB HyperX 540MB/s read, 450MB/s write.

My eclipse.ini

Adding more from a eclipse bug report I found felt like it made things a little bit worse:

I confirm my own experience switching between XML file tabs on Juno 4.2 SR1 under Windows 7/64.

My eclipse system is configured with 2g memory and most other applications (other than XML documents), including Java editing, debugging, etc., do not have such a heavy impact on performance when comparing Juno with Indigo.

For the first time after several months using Juno I tried going back to Indigo SR2, and I verified that switching between XML tabs is instantaneous.

I tried to change validation and other settings for XML but it seems this is a 4.2 issue, as the same XML files on the same workspace work 10x faster on Indigo...

Also: using classic theme.

Did something go wrong or untested in Juno?

Even if we find ways to fix this issue with the help of this and other forums, as a veteran eclipse user I honestly expect to be able to update to a new version without having to read hundreds of posts in order to make that version work...

Best regards,

Reuben

64 bit mac OS 10.6.8 w/8GB DDR3, just loaded up Juno and it's beach balls all the way. I was running Indigo previously, it was also slow to compile programs, even tiny ones (<10 lines of code), running only Eclipse and maybe 10 windows in a browser. In Juno, I have turned off animations, boosted the VM in the .ini, and activated the classic theme. Juno is not only slow to run programs, but will give me beach balls for simple things like clicking the mouse to place the cursor, typing one character, etc. Hope this helps the progression toward a fix.

A little quick feedback on this issue:

On my System (Win7 64Bit, Eclipse 4.2.2 64Bit with Java7u15 64Bit) this issue is definitely GONE!

Switching between java & xml files is almost "instant like", views are updated very quickly (specially the outline view), scrolling up and down in big files with hundreds of lines is really smooth (smoother than before and with no interruption)...AWESOME! Shocked

This make it even more fun & efficient to work with eclipse. Smile

Great work dev's and thank you that you have solved this problem (in my case, I can only speak for myself).

best regards...

Hello Folks. Pl dont waste your time with Appearances/Themes/Xmx etc. Somehow non heap memory consumption is very high. It seems it is also covered by garbage collection. Every time I open a page, I get a 5 second delay since the GC kicks in. So simply increase permanent space in eclipe.ini to something like 1G. Xmx can be 1G or even lesser as heap memory usage is not much.

Hi Guys

A fresh download (4.2.2) works perfectly. No matter what parameters, Java version, theme or whatever is set. Thats good.

After updating my 3.8 (Install New Software -> Juno channel) to 4.2.2, the same pain came back (executed with "-clean", other tips?).

Could it be that all this shit is dependent on a special plugin/component or bundle?
How do I find out where the problem comes from? Which log files should I check?

* Mylyn
* PDT
* Aptana Studio (wonderfull ftp-sync, is there any alternativ?)
* subclipse
* all stuff that are needed by these plugins (automatically installed)

Just my own experience.
I'm using Juno on a 2001 XP Pentium 4/1.6GHz/1GB RAM . . .
It was terribly frustrating starting up.
And also often in the middle of coding.
I did the things suggested by you folks, i.e. classic, disable animations, increase allocated VM etc.
But I think what was killing my performance was this goddam Comodo internet security pack I'm using at present.
Just seeing how Comodo's stupid file scanning process ("cavwp.exe") was using around 50-60% of CPU versus Eclipse's 5-10% made me wonder what the hell it was at. I turned it off of course -- at least until Eclipse was up and running.
I had similar problems recently with a "trial" version of Webroot.

So my advice is use a good anti-virus/internet security pack and monitor how it interacts with Eclipse at times of slowness.

Thanks to all for the speed-up tips -- they really make a visible difference and, like another poster said, I am feeling like the system is responding swiftly to my code rather than me being at the beck & call of a dragass machine.

As this is about "Eclipse GUI is very slow" I want to mention a bug in eclipse, which gave me a headache for weeks.

Any text-editor in eclipse is very very slow on Linux if "show whitespace characters" is enabled (https://bugs.eclipse.org/bugs/show_bug.cgi?id=320595),
because the method WhitespaceCharacterPainter.paintControl is slow.

It's calling 3 slow methods for every visible character on each scroll step:
* GC.getFontMetrics()
* GC.drawString
* StyledText.getLocationAtOffset
