Created attachment 175820 [details] large_project.tar.bz2 I saw an interesting performance issue, with resource delta iteration during a periodic resource change notification, while a large project was being asynchronously refreshed. Bug 245008 comment 41 There was a lot of CPU usage during the project import, and, every time I interrupted the runtime Eclipse, I saw that the NotifyJob thread was iterating in RefreshJob#addRequest and the RefreshJob#fRequests list had grown to 73k items. A CDT resource delta listener was iterating over the resource change event, calling IContainer#members() which resulted in a lot of time checking whether the path, or a parent of it, was already in the fRequests list: iterating over the delta calling IFolder#members() => RefreshJob.addRequest(IResource) line: 67 RefreshJob.refresh(IResource) line: 141 RefreshManager.refresh(IResource) line: 86 Folder(Container).members(int) line: 268 ... This can be reproduce by importing the attached project into a CDT (as CDT has a listener which iterates over the delta).
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
