Howdy,
I've recently installed OF on a pair of 2K3 STD 64 bit servers - all
patches/updates. Each has a Mellanox 25208 (128MB) dual port 4x SDR adapter.
For testing, these two machines are plugged into each other back to back with
OpenSM running on one. Everything seems to be functioning properly, however my
overall throughput seems fairly low for the available bandwidth.
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[204] local 10.21.0.10 port 5001 connected with 10.21.0.1 port 3381
[ ID] Interval Transfer Bandwidth

vstat shows:

It would seem that WSD isn't kicking in here at all given the results of
iperf/netio. Anything that I should check for? Adapter settings?
Any help would be appreciated.
