Ok - good news: it was just that.  I had a pending fix for Bug#73018
that caused the bad performance.  Without it I see a very good performance.

But if you want to give it a try, don't hesitate either.  If the user
happens to search for something like the user or group name in
file names, the behavior is annoying.  And a confusing surprise.
So even if it's a corner case, I think it could be worth trying to
improve this, given you have the time.
