That would not be a good idea, as the controller caches by the stripe. So a 32MB stripe would allow you to cache only two stripes. It also depends on what RAID level you are using. You probably wouldn't see any benefit beyond 1MB stripes anyhow. > Thanks, Simon, for a job well done. > > ================================================== > Raul Zighelboim rzig@verio.net Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
