"My artifacts" widget has severe performance hurdle. It's reported to take more than 40s for some users and according to slow queries log, it can take up to 200s!
While inspecting the query, we found that, in addition to performance issue there is a functional issue, the query is overfiltering "Assigned to" artifacts and report less artifacts than there actually are.
For the 40s user, we got better results (still 23s...) but the number of returned results is way too high (~2000 artifacts returned).
If obviously not usable to have 2000 artifacts on "My personal page", even if we manage to fetch the data faster. So the question is: how this widget is actually used or could be more useful by displaying less information ?
