 Eclipse 4.2 GUI is very slow [message #894739] |

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!

Thanks Thomas for this "hidden" tip with the shadows. 
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.
best regards...
Rico

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

unfortunately I'm gree, Juno is very slow and the bad question is that all the world waited so long this version 
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...
best regards

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.

Another big worsening is dragging and dropping views and editors, this feature is not slower....this feature became totally unusable
I continuously ask myself how it was possible get worse one of the best ide solutions present until today...shocked but I'm curious and a bit masochist to wait for next updates...

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
