If you are interested in gmirror software-raid performance, I put some bonn= ie=20 benchmark data online. I run the benchmark on a cheap none-raid=20 Promise-Ultra-133-TX2 aka PDC20269, which costs about 25 Euros: http://members.chello.at/freebsd-5.3/bonnie-gmirror/summary http://members.chello.at/freebsd-5.3/bonnie-gmirror/detail Cheers, ch=20 =2D-=20 Christian Hiris <4711@chello.at> | OpenPGP KeyID 0x3BCA53BE=20 OpenPGP-Key at hkp://wwwkeys.eu.pgp.net and http://pgp.mit.edu --nextPart1786940.dTjWZyVUIr Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBB+WO509WjGjvKU74RAg7cAJ9YH1PlOV7IrqEjcW7o2L1iGEiiSQCfWrks XDNq3/R6IBv95y7G9g7A0fk= =L9dD -----END PGP SIGNATURE----- --nextPart1786940.dTjWZyVUIr--
