hello list,
in the xfs faq i read elevator=noop is best when using ssd.
i have the gentoo system on a ssd, but the larger data storage partition on
softraid with some sata disks.
is elevator=noop in this combo still best?

thx for any cunstructive answer

marko

noop and deadline are best for SSDs. deadline is best for spinning
disks with XFS, especially in RAID. Stay away from CFQ as it kills
parallelism in XFS

thx grozdan,
but what, if i have mixed setup in a server ssd + sata ??

marko
