 =head1 PERFORMANCE NOTES
 
-L<Inline::C> is recommended for performance.  To enable it, create
-C<~/.cache/public-inbox/inline-c/>.
+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.
 
-If Socket::MsgHdr is installed (libsocket-msghdr-perl in Debian), the
-first invocation of lei starts a daemon, reducing the startup cost of
-for future invocations (which is particularly important for Bash
-completion).
+L<Socket::MsgHdr> is optional (libsocket-msghdr-perl in Debian),
+and further improves startup performance.  Its effect is most felt
+when using shell completion.
 
 =head1 BASH COMPLETION
 
@@ -117,6 +131,17 @@ C<contrib/completion/>.  Contributions adding support for other
 shells, as well as improvements to the existing Bash completion, are
 welcome.
 
+=head1 UPGRADING
+
+Since lei runs as a daemon, L<lei-daemon-kill(1)> is required to kill
+the daemon so it can load new code.  It will be restarted with the
+next invocation of any lei command.
+
+=head1 CAVEATS
+
+IMAP and NNTP client performance is poor on high-latency connections.
+It will hopefully be fixed in 2022.
