These results are surprising to me, since I have also run GRE over IPsec. While IPsec obviously does consume some CPU, the machine that you mentioned should be more than capable of saturating a 100 Mbps link. I would try running tcpdump on the traffic both inside and outside of the tunnel to see if you are experiencing a high rate of retransmissions, fragmentation, etc. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
