I've been having the same performance quirks... the zoom animation and a
few other things are *really* slow, but everything else seems to work
fine. (Except that sometimes the mouse clicks don't register correctly,
but as I recall, that's a problem with the X server, right?)
Anyway, I downloaded the Ticks program. I get one tick approximately every
ten seconds. Weird.
My machine is a Workgroup Server 7350, 180 MHz 604e, 256 Megs of RAM (of
which I give 64 Megs to MOL), running MacOS 9.0 on mol-0.9.39 on Linux
2.2.14 and the stock linuxppc-1999 X server.
