I ran some quick tests using LanTest - here are the numbers:
All numbers are in kb/sec. Test writes and reads a 3 meg file to the
servers. All servers are on the same ethernet, and are very lightly
loaded during the tests.
Centris 650 16/230 AppleShare 3.01
write 88.97
read 418.70
DEC 5000/240 32/2.6G, Prestoserve, Netatalk 1.3
write 212.30
read 339.36
Sun Sparc 4/110 8/500, Netatalk 1.3
write 95.35
read 194.70
Centris 650 20/230 Personal Filesharing
write 140.00
read 195.12
IIfx 20/120 Personal Filesharing
write 109.89
read 240.21
The outrageous read rate for the Centris Appleshare is mostly due to
the fact that the file was cached completely in RAM for the read
operation.
We regularly transfer ~60 megs of stuff to some 50-60 Centrises from
the DEC and it seems that the DEC performance does not degrade as much
as the Centris AppleShare Server.
Hope this helps
