I compared reiserfs with notails and with tails to ext3 in journaled mode about a month ago. Strangely enough the machine that was being built is eventually slated for a mail machine. I used postmark to simulate the mail environment.
Benchmarks are available here: http://labs.zianet.com
Let me know if I am missing any info on there.
