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.
