The *_RR tests seem to show a drop in througput and corresponding increases in service demand - could that be because things like TSO et al cannot mask much of anything in the way of a path-length increase? From the annotations, I'm ass-u-me-ing that NS was only used on the netperf side and not both netperf and netserver side? happy benchmarking, rick jones > These results are consistent with the ones previously made for ipv4. > > http://lxc.sourceforge.net/network/bench_ipv6_graph.php > > Thanks to Benjamin who did all the performance tests :) >
