You made a lot of tuning of the network driver while searching a solution to this problem. Could you share all the relevant settings of the ixgbe driver from /boot/loader.conf and /etc/sysctl.conf? I'm trying to fine tune the settings on a 16 core system but I have some doubt so I'd like to compare my settings with yours. I'm working on a high PPS router and I'm also interested to Luigi Rizzo's netmap code. I tried netmap with click for forwarding but unfortunately I'm facing some problem with route pushing from quagga. I had also to understand if is possible to link aggregate two ixgbe with netmap (using lacp). Thanks in Advance, Davide
