I'm not sure but you could maybe try disabling all but one of your CPUs and see if anything changes. It looks like you have at least 16 CPUs. On my machine, with 8 CPUs (2xquad core) I get roughly 150,000 PPS before I hit a similar single-CPU-bound network processing bottleneck (also with Intel=C2=AE PRO/1000 PT/Server) - which is too low for my needs so I'm searching for a solution. In my case I don't see transmission errors. --------------enigBEDEAAAD4EFBF68438E74D08 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJHXUyldnAQVacBcgRAhSxAKCCRAh6L0XvOFJzmfP9cjd5NIQc6QCcCtJF 9PauafcND6O9BSDmm/D3dLE= =Nz/N -----END PGP SIGNATURE----- --------------enigBEDEAAAD4EFBF68438E74D08--
