It's a bit old and for an old version of FreeBSD, but you can use it as a starting point: until you reach the numbers of PPS from those tables, you shouldn't worry :) There are not many SMP benchmarks there, but I think they show that, at least back then, it wasn't worth using on a router. The situation now should be better, but I don't know if anyone's measured it. --------------enig360EE1B53AE7796698509F44 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 iD8DBQFJnn1kldnAQVacBcgRAlE+AJ4rBp4qHJMdvNTr4bCtq4rzHJYyHACgx6P1 XE0P4OhAQp7bLAGIZ8wbAA8= =0Q1/ -----END PGP SIGNATURE----- --------------enig360EE1B53AE7796698509F44--
