If a NIC supports multiple queues, will they be used automatically or net.isr.numthreads needs to be increased? I have this situation on a machine with an igb card: irq256: igb0:que 0 103573 11 irq257: igb0:que 1 10094 1 irq258: igb0:que 2 18231 2 irq259: igb0:que 3 18186 2 This looks like the first queue is used ~~ 10x more often than the others. Is this a problem? --------------enigFB0266DA8881B747D8598E15 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9YqmcACgkQldnAQVacBcgAJwCfQl9c0+XHf62gcDf1Ucco3ljO CQkAoL5my4Klw0cmykDp6v1Itb116V3q =MjoA -----END PGP SIGNATURE----- --------------enigFB0266DA8881B747D8598E15--
