I don't remember the exact figures. But given that the mvs(4) sometimes hanged up (most of the time silently, really bad times would have drives flap in and out), I say that mpt(4) comes out on top easy. Other than that... My testing was done using all of my Gbit interfaces and trying to max them all at once, and I could bust out something like 300-400MB/s in pure transfer speeds using HTTP. I'm not sure if the zpool iostat are to be trusted, but I reckon mvs(4) would go up to 400MB/s while mpt(4) did go around 500-600MB/s... (take that with a healthy grain of salt) Cheers --=20 Stephane LAPIE, EPITA SRS, Promo 2005 "Even when they have digital readouts, I can't understand them." --MegaTokyo --------------enigE2F0C526CED020A9F7C85970 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk99zSsACgkQ24Ql8u6TF2NSHACgjpR5Gay3crFXh4dh10hW8YPX 12AAoMbBHsKohWxMlWrNtMSs9EBlKmUn =FgK/ -----END PGP SIGNATURE----- --------------enigE2F0C526CED020A9F7C85970--
