Since it was useful to you I tried another "unreal" workload :)). I
to play 9 .mov flix simultaneously using xanim. The combined size of the
is less than 20MB. I used the '+b' option of xanim so that all files
would be
sucked into buffer before playing. I am also using XFree4.0 if that is
of any
importance. I have put the vmstat log at the same spot as before:

kswapd was not nearly as much of a 'hog' during these tests but, still
too greedy in its cpu consumption. The swapping behaviour seemed very
to me. Maybe you could comment on it?

BTW: This "unreal" workload is not a problem with 2.2 or pre ~99

Take it easy,
