I'm wondering what the effective speed of 10Mbit Ethernet is. I've got a
DEC 3000/300LX that just isn't giveing me the kind of Xfer rates I expect,
and I'm wondering/suspecting there is a problem with my calculations.
Using a pair of PDF's totalling 24.6MB as my test I'm getting 8.34MB/Min,
yet I'd expect it to be closer to 72MB/Min.
The machine on the other end is a G4/450 PowerMac with 100BaseT, plugged
into a 10/100Mbit switch, the DEC3000 is plugged into a 10/100Mbit hub
which in turn is connected to the switch.
Of course part of this could be the 21064/125 processor, and part of it
could be the fact I'm using Appletalk.

I get 14.7MB/minute, copying four PDFs totalling 22MB from a
substantially slower Mac (603e at 180MHz) to a much slower (on-topic:-)

Doesn't look like it.

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.
