hello fellow ubuntu users!

I have a really big problem with my Eclipse Indigo running on Kubuntu 12.04 32bit, Dell Vostro 3500, Intel(R) Core(TM) i5 CPU M480 @ 2.67 (as cat /proc/cpuinfo said). It has 4GB RAM.

cat /proc/cpuinfo brings up the following:

java -version brings the following:

java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) Server VM (build 23.0-b21, mixed mode)

it's the Oracle Java, not OpenJDK.

I try to develop an Android application for GoogleTV and Eclipse is this slow, that it can't follow my typing (extreme lagging!!), but this issue makes it almost impossible!

here is my eclipse.ini file:

has anybody faced the same problems? can anybody help me on this problem? it's really urgent as I'm sitting here at my company and am not able to do anything productive...

Just a question, how large are the projects you are working on? It's acceptably responsive for me on small projects. Perhaps you could try breaking up projects in to smaller modules (I do get a bit of lag when switching from project to project), but it may help. –  hbdgaf Aug 2 '12 at 18:12
    
Are you maybe using the "Project Explorer" view with working sets as top-level elements? If so, that's maybe the problem. Either change the top-level elements to be projects or use the "Package Explorer" instead. –  htorque Aug 2 '12 at 21:43
    
can you try it with java 1.6 and report the results plz? –  danizmax Sep 13 '12 at 9:12

I had the same performance issues with eclipse on linux mint kde 13, I did some digging and it seemed that the default gtk theme oxygen was causing this. So I changed the theme to qtcurve and eclipse started to respond nicely. You might have to install qtcurve as it was not included in the kde desktop by default.

How did you change it to use qtcurve instead of oxygen as gtk theme? –  Jarl Dec 7 '12 at 9:05
    
You can change the theme under System Settings -> Application Appearance -> GTK+ Appearance –  Kamran Dec 9 '12 at 23:06
    
This answer works beautifully for me. To install qtcurve, just type 'sudo apt-get install qtcurve' in the terminal, put in your password, then change the settings in 'System Settings' as described above. –  LordOfThePigs Dec 31 '12 at 13:58

I think it is just eclipse that is slow. Do you think it is slower under Kde than under Unity?

I'm trying the following things out:

This is wrong. It used to work very fast for me until I did the update. Conclusion... some gnome gtk libraries are causing that. –  danizmax Aug 29 '12 at 8:29
    
@danizmax Gee is that the thanks I get for trying to be helpful and giving a fast response. Why don't you provide a more useful answer, rather than down-voting anything that isn't a perfect match. –  AmanicA Sep 7 '12 at 0:34
    
Sorry to upset you, I just down vote those answers that are really not true and can confuse others. Gee it's nothing personal xD –  danizmax Sep 13 '12 at 8:43
    
If it helps, as I already said, it stopped working for me when I updated Ubuntu, so it's either the kernel or some gtk library. Actually I'm searching for a solution right now, if I find one I'll post it here. –  danizmax Sep 13 '12 at 8:46
    
@danizmax I think it should be encouraged that people post as many different options as possible, let the best ones be upvoted. Yes downvote blatantly wrong/misleading stuff and it seems that is what you think of my answer, but I don't. The OP (@herom) didn't mention and upgrade/update so you can't assume that is when this started. Many things can make eclipse slow eg. Editing 3000+line java files, or plugin updates like projectlombok.org 0.11.2. I think a reasonable workaround when you don't know the real cause is running it from a ramdrive to get it super fast under the circumstances. –  AmanicA Sep 13 '12 at 19:55
