Thread-topic: httperf throughput



I am running apache and httperf on the latest Xen unstable.


When I have the webserver running in a single cpu guest I can barely get 720 Mbps over 2 nics (each 1 Gb). That is the throughput is about 36% of the native linux throughput. (I get line rate on native linux with the cpu being fully utilized). The guest cpu is 100% utilized while dom0 is about 80% utilized.


Said another way, I can get 2000 connections per second in Xen before the cpu chokes while in Linux I get about 7000 connections per sec. Is this what is expected.


Does anyone have similar/alternate performance data to share?
