When you have a large adopting product, with many plug-ins, the function: Help->About->Installation Details will hang the UI (i.e. the window won't repaint and the menu items will go white). On my reasonably fast system (Quad core Q6600) the hang lasts for 20 seconds. I think it is ok for the function to take 20 seconds (although faster would be nice), but it should not hang the UI thread, while it is running.

I can attached a Yourkit profile of this UI hang, if you would find that useful. Let me know if you would like it. (It is only 1.6 MB).
Susan, this looks to me like it's an issue with the implementation of p2's content provider, what do you think?
Any updates?
(In reply to comment #4) > Any updates? It would be useful to have more information. The Your Kit profile certainly can't hurt. Specifically, I'd like to know what query is being executed in ElementQueryDescriptor.performQuery, as this query seems to be taking all the time, and since we are only querying the profile's contents (vs. going to a remote repository), it's not clear to me why this should take so long. The installation details use the progress service's asynch content provider so that the UI will not hang as content is being fetched, so I'll also need to look at the use of the UI job here.

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.
