I'm running the 388 Linux-mt client on a P5-120 (no MMX) and a 486/66,
and I've seen slight speed increases on both systems.

If your keyrate dropped to under a tenth of its former speed, I suspect
that there's something else running on your system which is consuming
CPU cycles.  Perhaps you have a runaway (Netscape?) process.  Use 'top'
to see what's running.
