Juno performance is slow [message #901301] Fri, 10 August 2012 12:42 Go to next message
Eclipse UserFriend
Some feedback, as a grateful long-standing user and admirer of the Eclipse IDE for Java projects.

I updated from Indigo to Juno, and the user-interface performance dropped off a cliff. The UI has become incredibly sluggish: sometimes several seconds pass when switching between editor windows, views, etc.

I am running Juno on a 64-bit system with Windows 7 and JDK 6.

I have switched OFF all "Validation" checks except "Classpath Dependencies".

The only plugins I use are Subclipse, Sysdeo for Tomcat, and AnyEdit Tool.

My "eclipse.ini" is set as follows:

-vm
C:/Program Files/Java/jdk1.6.0_30/bin
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
-product
org.eclipse.epp.package.reporting.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-server
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xmn128m
-Xms1024m
-Xmx1024m
-Xss2m
-XX:PermSize=256m
-XX:MaxPermSize=256m
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled
-Xverify:none

Indigo was (and is) really fast - so I have gone back to it for the meantime.

Sincerely

Harry Mantheakis

We've seen a couple of reports like this, and I've witnessed it happen to another developer too on an fast 8-CPU machine with oodles of memory. It's definitely a real problem for some people, but the cause not clear. We need you to take some stack traces or fire up JVIsualVM and get some snapshots of the slow behaviour -- we can't reproduce it locally.

See the following URL for tips on what to do to report information:

Thanks. I have 8-CPU machine with 4 GB of memory, which is adequate.

I will follow up on this, and try to help if I can, next week.

I'm fan of Eclipse and Juno but it is really sluggish for me as well. My hardware is 4-cores CPU and 12Gb of memory. Also I noticed that JSPs are opened really slowly. If you have several opened JSP it start annoying.

Juno is very slow for me too. I'm back to Indigo for now.

Very very slow. With the previous version running the same tasks in the same machine much faster.

Back to Indigo too.

Just installed Juno 64-bit on a Quad-core i7, 16GB memmory, ssd. Very slow performance.

Slow here too, Alienware with dual i7s and 24 gigs of RAM.

The UI is sometimes, but not always, really slow when an XML editor is open. I've also noticed that at times the refresh dependencies icon flashes really fast for a little while.

Please install the feature patch mentionned in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=385272#c212 this should
solve most of your problems hopefully

Please see my other reply. This XML slowness is fixed with the feature
patch or if you use one of the latest 4.2.2 builds.

Eclipse is working much better now! I can open multiple XML files with no performance impact.

Thanks!

Used Juno in a new project for about a month.
Working with .jsp and .xml file is insanely slow. It takes more than a few seconds to switch from or to a .jsp/.xml file. When I switch to a .xml (springframework configure) file, I can see from the status bar that Eclipse is loading the .dtd or .xsd files. Yes, it's SWITCH, not OPEN; the file is already open in Juno.

In one case, I saw six eclipse.exe processes (each with 2MB memory in size) in the task manager when I was really annoyed by its slowness.

Now I'm switching back to Indigo.

Harry, I'd you try using the performance fixes? See the following link fr details on how to install:
