I have been running a series of custom benchmarks to see what
filesystems perform best for a maildir-based mail server.
So far, XFS with an external journal has by far the best delivery rate.
However, as the filesystem fills and delivery concurrency increases, the
time required to list, read and delete the delivered files slows down to
unacceptable levels. Is there anything I can do, settings to modify,
patches to try, to improve this behavior?
