I don't think you can validly conclude much from just one sample of each type. Try repeating those tests enough that you can do some decent statistics. Oh, and you should probably either discard the first few results, or else take pains to flush[*] the buffer cache between each run, so you end up measuring the same thing repeatably. Cheers, Matthew [*] Unmount and remount /usr/ports should do that I believe. --=20 Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate JID: matthew@infracaninophile.co.uk Kent, CT11 9PW --------------enig60433F2C77354510EA61B6FA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.16 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk+ZrQMACgkQ8Mjk52CukIykHwCfcLyHI/YWTMP03gs0COcUxj2i pggAn22xxUsr+K4Z9rE2sfDY5FO+N9+b =19uT -----END PGP SIGNATURE----- --------------enig60433F2C77354510EA61B6FA--
