If you add -f M netperf will then emit results in MB/s (M == 1048576). I'm assuming of course that the MB/s of Apache and nginx are also M == 1048576. happy benchmarking, rick jones -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
