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@866, at this level the system load is 100% of which ~80% is interrupt systemload :( Thanks, -Harry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBDFYuaBylq0S4AzzwRAhCuAKCBnr6hAuQR4GbW+7fBArqxTCLFJACgk1t/ 6Scl0QOZ49JhLM4xexKkRQQ= =FP6N -----END PGP SIGNATURE-----
