Struts Page Flow Editor Unusably Slow

Question

I find the Struts page flow editor unusably slow.
Opening a diagram takes ~ 30 s
Dropping something from the component palette takes 10s
Just selecting something takes 1-2 seconds.
Moving objects on the diagram takes so long it looks as if nothing is happening so you end up trying to move things twice.
All the diagrammers are slow, but this one is appalling.
My hardware is Pentium M 1.7Ghz 1GB RAM.
I have plenty of RAM free

Answer 1

Not many.
