-- Mentor used to have performance issues when there were several hundreds or
-  thousands of torrents.  So I wrote a patch for xml-rpc.el to add support for
-  Emacs built-in libxml support, which was helpfully merged by the xml-rpc.el
-  maintainer Mark A. Hershberger.  This improved performance by a factor
-  of 100.  Make sure you upgrade to Emacs 27.1, build it with libxml support, 
and
-  use the latest xml-rpc.el version to benefit from this speed increase.
+- Mentor can be slow if Emacs was not built with ~libxml~ support.  This
+  typically happens only when there are several hundreds, or even thousands, of
+  torrents loaded in rtorrent.  Use an Emacs built with ~libxml~ support to
+  avoid this issue.  (Support for ~libxml~ was added in Emacs 27.1.)
