Well, I think the CPU requirements depend on the size of the filter you
want to convolve with.  45 second sweeps seem pretty standard - recorded
at 16 bit and 44.1kHz that's a bit less than 10^8 data points.  So if 10
operations are required per point you get something less than 10^9, so
that would occupy a 1GHz CPU fully for one second.

With inguz I get maybe 10% CPU activity for a few seconds at the start
of each track, which fits roughly with the above - my server is dual
core 2GHz or so.  

Brutefir is supposed to be very efficient, so my guess is 500MHz is
more than enough, especially if your server is dedicated and you don't
use sweeps longer than 45s.
