John,What are your observations of how this code behaves on congested links. I expect that the sorting of received packets distorts the ACK clock and packet skew measurements reducing the ability to accurately measure the congestion window. Processing ACK packets in bulk is likely to produce a bursty transmission pattern which can result in overflowing the link capacity. As a result, fairness is reduced and packet loss might be increased.

Hi Ben,We have been importing these patches into our IBM internal OpenAFS 1.8.X builds for over a year and have had our busiest cells running these versions since fall last year. We hit some deadlock issue early on but that was fixed and I believe those patches made it to gerrit as well.I did the work to get the patches to apply to the versions of OpenAFS we are running, but I don't feel confident calling it a review. I missed the deadlock issue until we actually put it into production :).John Janosik jpjan...@us.ibm.com
