My bet would be that RAID-0 w/o LVM would give the best speeds Omitting LVM isn't an option, I'd lose all the flexibility that LVM offers. I don't see why RAID-0 should be necessarily more efficient than LVM, unless there's something superior about RAID-0's striping algorithms. I could do some before and after tests, but I'd first have the reformat the filesystems to remove any effects of fragmentation. If no one comes up with a good reason for keeping the RAID, I'll get rid of it, running bonnie++ before and after. --=20 Neil Bothwick Contentsoftaglinemaysettleduringshipping. --Sig_h7jQos.PnQcGennw.JK0vzn Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.3 (GNU/Linux) iD8DBQFGEgaeum4al0N1GQMRAvdZAJ4pDrpjp0Lsf7KWoU1aRkNHjp7RmACfV1uh cjezifeuDMzD+lLU+NgJ0sw= =KtFh -----END PGP SIGNATURE----- --Sig_h7jQos.PnQcGennw.JK0vzn-- -- gentoo-user@gentoo.org mailing list
