Description g m CLA 2013-08-07 09:47:32 EDT
I am using Kepler Release Build id: 20130606-0932, and I am finding the GUI to slow down after a few minutes of usage. If I try to type something in, it only appears after long seconds, the suggestions take 5-10 seconds to show up, pretty much everything slows down.

I use it in the following way:
# ~10-20 tabs open at a time, but it occurs with only few tabs open
# RSE installed with tabs open to the remote source
# J2EE perspective open
# Java and JSP files open
# The source is linked, and used to run the compiler in the original folder

Only restarting Eclipse solves the problem.

In which editor? Please take stack traces [1] while you wait and attach them here.

Only in Java editor. Will get the StackTrace when it's doing it next time. I suspect it has something to do with the Workspace being refreshed...

Is only content assist slower or does the whole workbench get slower - even after closing the editor?

Assist and even typing into the editor gets slower. E.g. I enter System.err.... and the text appears only after several seconds. 

It's like if the compiler was encumbered by something.

The compiler is not reacting/interfering while typing. Maybe you get close to the memory limit that you give to the VM.

I am running it on a 64-bit windows with 8Gb RAM with the following VM arguments:

--launcher.XXMaxPermSize
2768M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms440m
-Xmx2512m

I can't reproduce this using our current release:
