I have been working on a visualization tool that has 100's of nodes,
arcs, etc... I noticed much better performance under windows than on my
linux machine. I have created a GEF/Draw2D independent performance tool
that actually shows some performance numbers for the SWT Canvas widget
(this is the widget that GEF uses to draw on).
Basically this means that the performance problems are not in GEF. I am
just posting this note as an FYI for anyone doing GEF/Draw2D apps for
Linux. If you want to track this issue checkout bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=134760
In order to measure performance I ran linux and then windows on top of
linux (using VMWare). The windows machine showed better performance in
almost every category. I am not sure if this can be fixed in SWT or if
it is GTK specific. The SWT team is looking into this.
We also had a short discussion on platform.swt newsgroup.
Cheers,
Ian

Great work! Whether there are performance problems in GEF or SWT, creating
the test cases that show them is extremely valuable. If you want some more
ideas, I know there are about 6 method on GC that result in the construction
of a Pen on win32. I've always thought this might be a penaly when changing
multiple draw attributes like mitre, width, FG color, line dast, etc.
