Hi, I saw a post at http://lists.freebsd.org/pipermail/freebsd-net/2012-October/033660.html discussing performance degrade on ixgbe when enable TSO. We are experiencing the same issue on FreeBSD 8.2 with the latest ixgbe driver (version 2.5.8) from Intel. I am not sure if this is a driver issue or a system issue and if there is a fix for this issue? If yes could you please let us know where we can find the patch? Many thanks in advance! James Pan
