Linux has in the past been widely acknowleged as the fastest database
and mail server because of its fast asynchronous I/O, but I don't know
if that view is still valid with modern BSDs. These days they are also
capable of fast asynchronous I/O and their log-based filesystems have
the jump on any Linux filesystem as far as write performance goes.
