On eclipse 200411050810 (but i guess it is not specific to this build), I've noticed that when my target platform is pointing to a product that contains several 1000s of plugins (guess what I'm talking about :), the startup of eclipse becomes *really* slow. Note that that it was not my first startup with this target and that when I saved my previous session nothing wrong happened. My workspace was containing a few plugins including runtime (but nothing changed on disk). Here are two stacktraces of two different startup showing the work being done by PDE. 4XESTACKTRACE at java/util/zip/ZipFile.getEntry(Native Method) 4XESTACKTRACE at

This big computation is due to lack of caching which will be addressed in bug 66189 *** This bug has been marked as a duplicate of 66189 ***
