You bring up a long-standing problem here. :-)  Without an automated
performance test suite, all we can go in is the system "feel" and
"snappiness" when trying to use it.

I would still like to put together a test suite (ideally generic enough
that we can also benchmark Qt4/Qt5 for comparison purposes), but don't
have time at the moment with trying to get R14 out the door and all.
