Well, one probably big difference is that I'm running OpenVMS 7.2 w/DEC
TCPIP on the DEC 3000/300LX. Also Netatalk might give a lot better
performance than Pathworks does. The same machine also gets pretty bad
Samba performance though. RAM isn't an issue as it's got more than enough
for what it's doing.

It's kind of frustrating knowing I'd get better performance out of a cheap
UNIX box, when I want to use my OpenVMS cluster as a home fileserver. I'm
scared to even consider using the on-topic MicroVAX 3 or VAXserver 3100/30
as a front-end, but am wondering how the AlphaStation 200 4/233 or
AlphaStation 500/333 would handle the job.
