Thank you for the offer, but I thought people had some simple test results
in mind. If you next time use rdump or large NFS transfers to another GbE
connected (and fast enough) box just watch the system load (I use systat
-vm 1) and see what card causes what interrupt load. em cards can't
transfer (real files over FTP/NFS) more than 200mbit/s on a
Coppermine at 866, at this level the system load is 100% of which ~80% is
interrupt systemload :(
