Chuck, Thanks... That is the intention of the filesystem, it is going in a web server. -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Chuck Swiger Sent: Thursday, March 16, 2006 5:43 AM To: Don O'Neil Cc: freebsd-questions@freebsd.org Subject: Re: Raidtest/3Ware 6000 Throughput Don O'Neil wrote: [ ... ] > Does this seem accurate?

It does not astonish me that you get 5 MB/s on a RAID-5 config, although if you used SCSI and/or a real HW RAID-5 controller with significant cache (ie, 64+ MB) that would help the performance by quite a bit. Use RAID-5 for read-only or read-mostly situations and you'll be better off; use RAID-10 for write-heavy filesystems instead. -- -Chuck _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
