Description Jan Becicka 2003-08-19 10:46:52 UTC 
I must wait sometimes for seconds for IDE to respond.
I did a thread dump. I hope it helps. There is
probably some bug in looks, or in VCS module.
Please check it.

Comment 2 Vitezslav Stejskal 2003-08-19 13:01:04 UTC 
My experiance is that combination of projects and vcs has drastic
impact on performance. I don't know why. The FTD shows that vcs fires
annotationChanged events which causes looks to redraw names of file
nodes. The other active thread which asynchronously redraws nodes
(probably invoked by events fired from previous one) spends its time
in reading the registry (looking for looks and instantiating them),
this should be improved by caching in NamespaceSelector (Hrebejk has
this almost done).
Comment 3 Jan Becicka 2003-09-10 16:10:22 UTC 
IDE is slow even if CVS filesystem is not used. BTW see issue 36011
Comment 4 Vitezslav Stejskal 2003-10-04 12:11:47 UTC 
Now the situation should be better - LookSelectors are rewritten and
properly cache Looks, issue #36011 is fixed. Could you please verify
that IDE is faster now or describe what exactly is slow? (or make more
FTDs) Thanks.

[200310060000] IDE is definitely faster
