Measurements are on 10Gbit/s with ixgbe NICs.Could you please share other HW details? I wonder how much CPU power one needs for such a throughput?
If you would like to get to know the exact specifics from the bug report, resp. numbers from the commit message, I refer you to Peter's setup, i.e. he used ixgbe NICs as these are one of the few with SCTP checksum offloading available.
