10Gbe Tuning?
-
I set the MTU on these to 9000 yesterday and 9000 on the iperf servers I'm using and was able to saturate (9.5Gb/s) the link. So I'm pretty sure I'm hitting just one interface. But going back down to default of 1500 MTU, knocks the speed down quite a bit. I think I've done everything correctly, but may have overlooked something quite obvious.

it's trivial to saturate a 10Gbps link between two machines, using much less hardware than you have, without changing the MTU.

I understand. But after following post after post and blog after blog, it just seems that my TCP performance test is a little low. Is this expected? I'm also shooting for over 10Gb/s with LACP, but I'm just not getting that. Not quite sure where I'm going wrong here.
