Description Eric Jodet CLA 2007-04-11 05:06:52 EDT 
Version: 3.3.0
Build id: I20070410-1043

J2RE 5.0 IBM J9 2.3 Windows XP x86-32 build j9vmwi3223-20070201

Running Eclipse against the monster workspace: closed a single project (right-click org.eclipse.update.configurator --> close project)

Close operation sounded like hanging and took more than one minute.
I'll attach jvm snapshots

Restarted the workbench and tried to re-open the project I just closed: same issue --> the operation took a lot of time (to_be_attached snapshots)

Actually, the cause of this bug is the same as in bug 145329 (i.e. source attachment is the root of the slowness).

Marking this bug as a dup of bug 145329 since bug 145329 is the oldest.

Eric can you please try your scenario with the patch attached to bug 145329 and report here whether it improves opening/closing of a project ?
