Sure, you measure it ;) ... no, of course it is more expensive to update a 64bit counter on a 32bit arch, but the key (once again) is descision: While (almost) all of the pf counters are 64bit types you can configure it not to use the loginterface or whatsoever more. So it's up to you: You need 64bit counters? You shall have them! You need *fast* 64bit counters? AMD sells nice processors (they say)! ... you get the idea. --=20 Best regards, | mlaier@freebsd.org Max Laier | ICQ #67774661 http://pf4freebsd.love2party.net/ | mlaier@EFnet --VS++wcV0S1rZb1Fb Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAVk0NXyyEoT62BG0RAg7jAJ9h9v2znJoFIgCsOgbnsE/pHzlXIwCdHfsb xwdF4AKzvRchzAt3lX8Qvdk= =48Om -----END PGP SIGNATURE----- --VS++wcV0S1rZb1Fb--
