@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!

Since SR1 & 4.2-M-build (M20121003-1200) the UI response is noticeably faster than before!
Thanks, keep up the good work!

I love you guys! =)

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.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=385272#c212

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

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120522-1813

-XX:PermSize=1024m
-XX:MaxPermSize=1024m
-Xverify:none
-XX:+UnlockExperimentalVMOptions
-XX:+UseG1GC
-XX:+UseFastAccessorMethods

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

-Xmn128m
-Xss2m
-XX:CompileThreshold=5
-XX:MaxGCPauseMillis=10
-XX:MaxHeapFreeRatio=70

The patch (update site: http://download.eclipse.org/eclipse/updates/junoSR1Patch-tmp )seemed to have solved this issue. (Also works on release from june, so you don't need to download eclipse SR1). Thanks a lot Smile

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

Did you tried Juno SR2 builds - we are at RC-candidates for them as of
now - Are they still slow?

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...

Enrico R.

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.
