samba - Mar 2003 - To all who helped with Ext3fs/ReiserFS Performance Enhancing

First off, thanks! :)

	It appears that the issue could be a bad switch. At this time, I
have turned down the server's NIC to run at 10baseT-FD and the
performance has seriously increased. It now takes roughly 25 to 35
seconds to copy and 8mb file to the server, but it now takes a little
longer to copy a file from the server.

	So, we are now in the market for some far superior network
switches.

	Thanks again.

If you don't need anything fancy, I've had excellent performance from
the
StarTech Desktop switches.  These are dirt cheap (often comparable to a
hub) and have always worked well for me.

Sometimes neither the NIC nor the switch is entirely to blame for
speed/duplex mismatches, some cards and some switches just don't seem to
negotiate properly. I had that problem at one job with Sun E450s and
Cisco smart switches - the switches and the Sun hme cards both worked
fine, but they would never negotiate duplex properly. Forcing the NIC
and the port both to 100/full fixed everything. If you can do that you
won't have to buy and install new hardware, at least not right away.

Of course, if you can't force the settings on your switch that won't
help you any, and as I recall not all Linux NIC drivers support forcing
speed/duplex so it might not work with a different card either.
