Folks, I have posted this before but got no good response and i havent had time to chase it. While doing some batching tests with pktgen and then with a simple client server app with udp, it does appear that the clock source used matters. Here are some basic runs with plain vanilla 2.6.22-rc4 runs with udp. There are five runs per clock source and each result is in Mbps.
acpi_pm: 108, 110, 111, 91, 108 tsc: 143, 108, 161, 129, 108 jiffies: 132, 138, 132, 146, 150 jiffies produces better results than tsc which produces better results than acpi_pm. Second issue: I cant consistently get two reboots to always boot with the same clock source. Any ideas whats going on here? I havent tried with latest tree. PS:- These results are very easy to validate with iperf or netperf. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
