Thanks Guto. If anyone else will send Xanadu test run times to me or 
post them to the list, I volunteer to maintain a results file...

I propose that xanadus.sco be the score (as opposed to xanadul.sco)
and that the orc be xanadu44.orc and optionally xanadu08.orc.

regards,
PW

I think the Xanadu piece is a much more realistic test of what I 
want to do with Csound - intensive computations for fairly long 
pieces, not simple synthesis or processing of short audio files.

The other problem with the original set of benchmarks is that the 
CPU time taken to calculate them may now be just a fraction of the 
time spent to write the results to disk.  Since the benchmarks are 
usually performed one after another, it would not be surprising if 
the later benchmarks ran slower than the first ones because the RAM 
cached disk buffers of the first benchmarks' outputs are being 
written to disk while the later benchmarks are being run.

An easy test for this is to re-order the benchmarks and see how the 
times vary.

I am not quite organised to do this, but will report on it when I 
am.  I now have a 200 MHz 256kbyte cache Pentium Pro running 
happily and supprisingly cooly at 233 MHz.  It is running RedHat 
5.1 Linux.
