You may want to retry without LACP. A long time ago on Linux, the bonding driver used not to propagate NIC-specific optimizations and resulted in worse performance sometimes than without. Also I don't know if you're using VLANs, and I don't know if openbsd supports checksum offloading on VLANs, but that could as well be something which limits the list of possible optimizations/offloadings that normally result in lower CPU usage. > Card seems to be OK.

Then make sure to use a distro with a kernel 3.10 or above, that's where you'll get the best performance. > Btw, where Pavlos reported his test results? There in list or somewhere else? It was posted one or two weeks ago on this list, yes. I must say I was quite happy to see someone else post results in the order of magnitude I encounter in my own tests, because at least I won't be suspected of cheating anymore :-) Cheers, Willy
