Checking the above reveals that I measured B<->A using the main-network interface. Repeating the test with the direct connect interface gives a bit lower figures (810 Mbps transmit, 720 Mbps receive).
Oh, the direct connect is eth0 and the main network is eth1.
Any ideas on how to improve B's performance would be very welcome. It appears you need to check the direct connections cable. That would appear to be the "weakest link". http://www.sql-server-performance.com/jc_gigabit.asp
Hi Joe, I'm not sure what I'm looking for there? The interfaces are running at gigabit rate and there are no errors logged, so the configuration appears to be OK, to me at least? And two similar systems with similar cables behave the same, which seems to eliminate specific hardware/cable faults? The cables are cat 6. Thanks, Dave
