It turns out this was mostly a false alarm.  Sorry for making an issue
out of it.  Last night I made the leap and upgraded all 5 production
myth boxes to 0.22.  With my reasonably powerful master backend (Core
2 Duo E5200) and a reasonably weak frontend (IONITX-C), bringing up
the Recordings page with almost 1000 recordings is pretty much as fast
as in 0.21, about 2-3 seconds.

I still wish I could get some visual feedback during this 2-3 seconds.
 It seems like changing the button background image after it is pushed
would be good feedback.  But I haven't managed to see any effect of
entering the "pushed" state.  I tried adding something like the
following to the mythuitheme.mainmenu.menu.buttonitem section of
  <state name="pushed">
    <imagetype name="background">
      <filename />
to try to make the background disappear whenever a menu button is
pressed, but nothing happens.  Is the "pushed" state supported?  Are
there any known working examples in some theme?
