Sure... I was curious what sort of difference I'd get by comparing dos 
csound/win95 csound/linux csound csound/linux & X csound... I tried 
running the currently available benchmarks and everything went so fast I 
wasn't sure what, if anything, to conclude.

Another suggestion: I wouldn't mind some benchmarks for testing realtime 
capacity... RTCmix (cmix hacked to give realtime output) has a little 
benchmark (? more appropriate term for realtime output??) test that just 
adds oscillators one at a time until your output gets bad... 
so your benchmark score is the number of successful simultaneous 
oscillators you got.
See http://www.panix.com/~topper/Cmix/benchmarks.html

They also have links to an experimental compiler that allows pentium 
optimization-- this might be useful to folks trying to squeeze more 
performance out of linux csound on pentium boxes.  For RTCmix the 
reported realtime performance increases range from about 9% to about 20 
% ... the question, of course, is whether you can get it work without 
intolerable amounts of instability... I haven't tried it (yet).
