Andrew:

Up until the mailing list traffic and patches slowed down, I was testing
it continuously with a heavy stress load that would bring the system to
its knees before the splitlru and unevictable changes.  When it would
run for days without error [96 hours was my max run] and no further
patches came, I've concentrated on other things.

Rik and Kosaki-san have run some performance oriented tests, reported
here a while back.  Maybe they have more info.
