We're running ~12 IBM 55sx's with 16/4 Mb token ring cards w/ FTP
Software's PC/TCP for token ring.  The cards are set for 16 Mb.
The only unix machine on the net is an IBM RS/6000.  The net is
independent - no gateways, bridges, etc.

ping reports 25 ms consistently from pc -> pc, pc -> rs6k,
varies between a low of 4 & a high of 80 ms for rs6k -> pc.

ftp runs at 50 Kbytes/sec for all combinations - pc -> pc, pc -> rs6k,
rs6k -> pc.

Now, it's possible I'm wrong, but these numbers seem a triffle (8-)) on the
slow side....

Is there anyone else out there w/ a similar setup?  What kind of times
are you getting?

Any suggestions?  Even a little bit of pc/tcp or netbios source code
would be appreciated - I'd like to eliminate ftp as a factor.

thanks,
   horkan
