so here's a potentially interesting idea. Since you are running plan 9
under Linux with 9vx, consider using the TAU toolkit to measure it.

we've used these tools to optmize an MPI library and they are quite
powerful.
TAU is good. There's also a Sun Studio Performance Analyzer that, to
my taste,
is a bit more tightly integrated than TAU and seems to be more scalable:

In fact, Ron, now that you've mentioned it -- I'm going to try the
PerfAn
on 9vx myself ;-) And here's the question for you: how representative
the behavior of 9vx is supposed to be of the regular Plan9 kernel?
Thanks,
Roman.
