Hello Otto, Thanks a lot for the detailed answer! I guess that deleting old messages in your system is a cron job. Am I right? When you runs that job? What load do you have then? > The speed is directly proportional to the number of files > in the Maildir, specially when IMAP threadsort and the > likes are enabled.

I'm curious what time your user needs to open his folder with 15,000+ messages? Has he to wait a few seconds or rather a few minutes? :) > 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. Thank you for the info! I need to do my own benchmarks now :) Best regards, Pawel ------------------------------------------------------------------------- Take Surveys. Earn Cash.
