I have been experimenting with the `cdspeed.zip' routine
available on garbo.uwasa.fi.  This routine was apparently
not designed to test above 150k/sec, but in any case it
indicates a top `Data Streaming Xfer rate' of ~320k/sec
for my drive.

The cd-rom is a NEC CDR-510 3xi, hooked to a Pro-Audio
Spectrum 16, on a PCI DX2/50.

Shouldn't this drive be capable of ~450k/sec, and what is
the most likely bottleneck:  the soundcard, software driver,
or CPU?  I'd appreciate any tips or pointers.
