That should be enough of a system for your stated needs. :-) Fifty heavy-duty users with IMAP/SSL connections, large INBOX and other often-used folders, and aggressive clients which open multiple simultaneous connections might use up lots of CPU at times though. > But what I'm really trying to get at is any file-system performance > tweaks that would help in this situation and that would perhaps apply to > more general, higher-volume situations too. On my home system, a DELL PE2650 with PERC 3/Di SCSI RAID controller, /var has 16384 block size, 2048 frag size. With FFS it's a compromise between the size of the filesystem and the size of the average file. BTW, you can get a similar machine for $600 or less on eBay these days. -- Greg A.
