Thus spake Ryan Dooley <ryan@third-man.com>: > I'm looking for recommendations on the newfs options for a 1.0TB file system > for say /home (it's a fileserver for 52000+ accounts that range from having > 4k to 40GB in their directories.) > > When I initally created the file system, the options I set are: block size of > 65536 and a fragsize of 8192. IIRC, block sizes greater than 16384 can cause significant buffer cache fragmentation, which can reduce I/O performance. Moreover, blocks that large will waste space and I/O bandwidth unless most of the files on the disk are very large. A smaller setting, e.g. the default, is probably more appropriate.
