Martin, and others:
Be very sure, on ours the ports appeared to work correctly with the 3com
driver,
under further testing, the 3com driver is doing something wrong and
working much
slower that it should be. Things were not noticable under normal
network use,
under NFS with the client running sync and the server running async the
write speed
is about 10x slower on a S2562 machine (client) vs. any other machine we
have with Intel
EEPRO ethernet cards. This was tested using the same server machine for
both
machines.
Copy of an 80 mb file from an nfs server back to an nfs server:
The eepro machine
file copy 25.58,18.49(probably cached read),19.06
seconds
write only test: 9.0MB/second on a 200MB write.
Beckers 99Uc driver
file copy 27.98,18.92(probably cached read),17.82
seconds (driver gets errors and stops)
write only test: 10MB/second on a 200MB write,
machine started getting transmit timed out
after 930MB, apic or noapic does not
seem to matter, we can duplicate
this one fairly quickly.
3com driver (3c90x 1.0.0.i)
file copy 52,47,44 seconds
write only test: 1.56MB/second on a 100MB write
On the write test, I tested the eepro machine, then waited a couple of
minutes, and tested
the 99U driver, and then immediately tested the eepro machine again, and
the second
test results were consistant with the first test, this was to verify
that one test was not appearing
to affect another.
