performance in pd - audiobuf, etc

	Perhaps you could dual boot to Linux?  I don't have any latency data for PD
on Win2000, but if you'd like to write a latency test patch, I could run it
on my system and send you the results?

	I've wanted to test this since applying the kernel low-latency patch, and
have never gotten around to it.

	I have an Athlon 600, 64MB Ram, Redhat 6.2, Kernel 2.2.16 with the
low-latency patch.
