Hi,
I'm observing poor performance while editing Java code using
Eclipse 3.0.
If I make an update to any text in the Java Editor View, the Eclipse
platform hangs for about 5 seconds, before blinking the cursor and then
allowing me to make some more modifications. Each time, I have to wait 5
seconds between keystrokes. I think that I have a 2 second window to type
what I want, before the computer freezes up for another 5 seconds.
As you can see, its not quite workable !!
There are approximately 8 working projects in my workspace.
My machine is an AMD Athlon XP at 1.6Ghz, with 512MB DDR RAM, Asus
motherboard with nVidia graphics, running Windows Server 2003. The server is
not configured for any networking services and is quite fast stand-alone.
If I open a simple java project with about 100 or more lines of code, I dont
find any performance problems.
The problem is with plug-in projects with classes generated from an EMF
model, the Omondo EclipseUML plug-in and VE1.0M2, installed.
I have enabled, run in backround option for Eclipse and also disabled the
Automatic Build option.
Has someone else experienced similar problems ?
Can anyone suggest a workaround to improve editing performance /
Thanks and I hope to hear from you soon !
Best regards,
Elvis Dowson
-------------------------------------------------------
My installation details are as follows :
- Eclipse 3.0 full install with EMF 2.0.0 and GEF 3.0.0 SDKs release builds
- VE 1.0M2
- Omondo EclipseUML plug-in
(eclipseUML_300_studioEdition-installer_1.0.0.20040719)
- FeeMem 1.0.0 plug-in ( Freemem not acively enabled in a view. )
- Sysdeo Tomcat PluginV3 ( Tomcat disabled )
Memory consumption by the javavm is around 128MBs !!
Total system memory utilization is 320MB ( total installed RAM is 512MB ).
I notice CPU peaks whenever the system hangs. Is there some background
process that's running inside Eclipse that's very CPU intensive ? Can I run
a profiler on the Eclipse code base and try to locate the method that's
causing the system to hang for 5 secs, between keystrokes ?

Did you try to start eclipse with more memory than 128M ? (eclipse.Exe
-vmargs -Xms128m -Xmx512m for example with sun JRE).
Are your source file in a networked folder ?
I notice some issues like theses but it occur after a long use time or
when class are compiled externally (ex: ant task). In this case, eclipse
seems to dislike anyone modify his classes...
Can't help more, sorry.

Sounds like one of the extra plugins may be interfering.
Can you try disabling the extra plug-ins?
E.g. rename their plugin.xml to plugin.xml.off, and run eclipse with -clean
to get it to pick up the changes.
