Greetings.

I have been running a series of custom benchmarks to see what
filesystems perform best for a maildir-based mail server.

	http://untroubled.org/benchmarking/2004-04/

So far, reiserfs has by far the best reading rate, but has serious
problems when more than one writer is trying to fsync concurrently.
Also, adding an external journal actually slows down the procedure
instead of improving performance.  Are there any configuration changes
or patches I should be trying to improve write performance?

Thanks.
