VE performace [message #119342]

Hi, I love Eclipse, however I find that the performance of VE is still a
lingering problem for me, and in fact has gotten worse with my switch to
linux. First, some platform info:

Eclipse
Version: 3.1.2
Build id: M20060118-1600

eclipse.vm=/opt/j2sdk1.4.2_10/bin/java eclipse.vmargs=-Xmx512M

EMF 2.1.0
GEF 3.1.1
VE 1.1.0

running on linux - Ubuntu Breezy (5.10) with Sun J2SDK 1.4.2 dual boots to
Windows XP with exact same setup

system is P4 3GHz 1GB ram, 2GB linux swap partition (unused according to
System Monitor)

hosts: 127.0.0.1 localhost

Eclipse on Ubuntu was installed manually at /opt/eclipse/ and Sun JDK is
set as my default java - and Eclipse is using this one. I read that this
is the preferred install method, as the Ubuntu packaged Eclipse can
exhibit some unexpected behaviour, such as launching under GNU java
regardless of settings. I have set up multiple Extension Locations so that
I can launch Eclipse with only VE and no other plugins/features to slow it
down.

My goal is to do swing development on Ubuntu, since I find that most
development functions on Ubuntu are WAY faster, however VE on Ubuntu is
actually quite a bit slower. The configs for the winXP and Ubuntu are
identical.

Does anyone know why VE would be considerably slower on linux? Or if there
are tricks/hacks (besides pausing gui rebuilding) to speed up VE?

On a different note, in a JTabbedPane, under WinXP I could simply click
the tab I wanted to work on and VE would rebuild the gui to show me that
tab. Under Ubuntu, clicking the tab does nothing. I have to right-click
the JTabbedPane and select Switch To, select the desired tab. Then I have
to pause and resume VE to get it to actually display the tab. So clearly
there seems to be some real differences between using VE in WinXP and
linux.

Thanks for your thoughts...

Greg

Greg,

You're not the only one that noticed a significant performance reduction
when using Linux. One thing that you can do to speed things up is to
close the Properties view when you're not using it (you can show it
again when you need to from Window->Show View->Properties). Details of
this and other investigations about why VE is slower on Linux are on
going in this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=104998

The tab selection behavior difference sounds like a defect - please open
a bug report in VE's bugzilla:
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=VE

Thanks!

Selecting JTabbedPane tabs directly wasn't added until 1.1.0.1. You said
were using 1.1.0. Could it be that you have 1.1.0.1 on Windows and 1.1.0
on Linux?

Great tip... getting rid of the properties window resulted in a big speed
improvement.

Thanks

Right you are. It seems that VE 1.1.0 is the latest available (for linux)
via the VE update site. Is that correct? If not, do you recommend manually
updating the VE version?

Try updating again, unfortunately 1.1.0.1 only shows up after installing
1.1.0.

Hmm... Seems a bit odd that the initial VE install from the update site
would install the second most recent version.

Thanks again for your help.

The problem is that the main eclipse site (which is the default one)
only has 1.1.0 on it. The actual VE update site is a different one, the
1.1.0 points to the real update site for VE, which is where 1.1.0.1 is at.
