We have both aproaches, NFS and direct. We have tell courier to limit messages to 16M. We have users which never delete mail (we force the INBOX to have messages not older than 1 year, 1 day for Trash) and I have seen like 15,000+ files in some folders for users who never delete mail. The speed is directly proportional to the number of files in the Maildir, specially when IMAP threadsort and the likes are enabled. We have IMP v3 and v4 and v4 is 10x slower than v3 when accessing large maildirs with equivalent settings, so client matters too. We tried ext3 and reiserfs and after some benchmarks and torture testing decided for XFS, 2.5 years ago ext3 have some problems with heavy concurrency and some kind of superblock mismatchs after long usage, I must say all those problems no longer are the case for recent 2.6 kernels. -otto ------------------------------------------------------------------------- Take Surveys.
