I use netperf which is a pure network traffic tester I also just use basic 'ab/apache' tests which would also test HD/IO if getting large files. For the 'em' driver I have seen some posts/cvs commit updates to the driver saying it now works better without polling then with polling. I think this is in -stable but it might just be in current. I haven't done any testing for a while. OxY wrote: > i changed sk to em. > how could i measure speed or benchmark the network performance? > > ----- Original Message ----- From: "Bjoern A.
