 =head1 PERFORMANCE NOTES
 
-L<Inline::C> is required, lei runs as a background daemon to reduce
-startup costs and can provide real-time L<kqueue(2)>/L<inotify(7)>
-Maildir monitoring.  L<IO::KQueue> (p5-IO-KQueue on FreeBSD) and
-L<Linux::Inotify2> (liblinux-inotify2-perl and perl-Linux-Inotify2 in
-.deb and .rpm-based distros, respectively) are recommended.
+L<Inline::C> is required on BSDs and can speed things up on Linux.
