A better benchmark would be to create a ton of itty bitty files like from a mail server... the reason there isn't much time diff between the two is because you picked a pretty CPU intensive task to benchmark. Try something w/ more files, that are created more requently. Toss together a quick program that forks off 20 copies of=20 itself that write 500byte files full of zeros and then deletes them... =20 you should see a pretty decent sized difference. -sc --=20 Sean Chittenden --qDbXVdCdHGoSgWSk Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Comment: Sean Chittenden iEYEARECAAYFAjuNiYcACgkQn09c7x7d+q0PbgCaAqlV8gPw1IRYDi1O9so+/XH1 6DkAn0y+/B+apm7lmG9zJPcrd8jaPCpm =i5vC -----END PGP SIGNATURE----- --qDbXVdCdHGoSgWSk-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
