ReiserFS for scalable and high load SMTP servers

We have seen great performance on using ReiserFS for mail system spools and in our tests ReiserFS file system spool for Postfix queues was very fast. For best performance we used

notail, noatime mount options in /etc/fstab file.

Full example:

/dev/sda2/usr reiserfs notail,noatime,rw,auto 0 0

notatime – turns off atimes calls, reduces IO and greatly increases file system performance
notail – increases performance of ReiserFS especially for small files – works great for mail servers, web servers and caches. This option disables file pckaging in tree.
