On what justification? Switching the default involves demonstrating that the new default is better than the old one, and simply "we've implemented more features" isn't good enough IMO. The last set of measurements I recall seeing said that credit1 and credit2 were mostly kneck-and-kneck, but there was still a noticeable difference in credit1's favour when it came to aggregate small-packet TCP throughput, and no benchmark where credit2 was clearly a winner. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
