I would like to better understand ext2/3's performance characteristics. I'm specifically interested in how ext2/3 will handle a /var/spool/mail directory w/ ~6000 mbox format inboxes, handling approx 1GB delivered as 75,000 messages daily. Virtually all access is via imap, w/ approx ~1000 imapd processes running during peak load. Local delivery is via procmail, which by default uses both kernel-supported locking calls and .lock files.
I understand that various tuning parameters will have an impact, e.g. putting the journal on a separate device, setting the noatime mount option, etc. I also understand that there are other mailbox formats and other strategies for locating mail spools (e.g. in user's home directories). I'm interested in people's thoughts on these issues, but I'm mostly interested in whether or not the scenario I described falls within ext2/3's designed capabilities.
