At 1TB the drive will take very long to fsck if the server ever crashes or looses power. If this is a problem you should look into using gjournal(8) Not sure off hand why it would be so slow, but keep in mind raid5 isn't particularly fast for writes Rich Fairbanks wrote: > Hi, > > I'm new to FreeBSD (and UNIX in general), and I have read through the > handbook and various websites to gain some insight on this question, but > haven't found a concrete solution yet, and I'm hoping you guys can help. > > I'm wanting to build a FreeBSD 7.0 based file server for a small/medium > company that I work for and I've got the box up and running, samba is > working fine, the only problem that I can see is that the array that I > installed (3ware 9650SE) with 3 WD 1TB SATA drives in RAID 5 seems to be > performing very slowly.
