One subsystem passing the data to another subsystem..well it seems logical that you would gain performance if you could exclude one of those. Actually I'd be glad to read some results from a "Fake RAID-0 vs LVM" tests. My bet would be that RAID-0 w/o LVM would give the best speeds -- Best regards, Daniel -- gentoo-user@gentoo.org mailing list
