cpu0: Intel Pentium III (Coppermine) (686-class), 996.79 MHz
total memory = 255 MB
avail memory = 233 MB
using 3294 buffers containing 13176 KB of memory

(but this is my test machine, host A below is a PPro with 64M)

No paging.

(for later down:)
100BaseTX ethernet via HP switch. Everyone running full duplex on
fxp and ex NetBSD ethernet drivers

Path of least resistance:

The mpg123 I want to replace runs as a "service" (part of a house audio 
system) but it ties up /dev/audio. I'd like to use festival on the same 
audio port, but without stop/starting the mpg123 service. The easiest 
way to go about doing this, since festival uses NAS, was to convert to
using the NAS version of mpg123.  I was hoping eventually to recompile
KDE/artsd with NAS support as well.

I just now checked from host A, and with a different audio card,
I have the same audio quality issues running mpg123-nas from a remote 
host, to my workstation where nasd is running, and the same if I reverse
the client and server hosts.

And now, unfortunately, to add to the story...
With some .wav files from host A to my workstation, auplay also shows 
the same poor audio quality issues...

So now I'm thinking it's nasd... am I outside the expected performance 
parameters of nasd?
