Alexey Verkhovsky, the new foreman on Instiki is helping pushing me from behind to get RedCloth 3.0 stable. (The latest release is within hairs!!) And he’s reporting a speed increase I didn’t expect, since RedCloth handles two kinds of markup now.
In this test of mine, 357 wiki pages (677 kb) are converted to HTML.
49 sec by RedCloth from CVS HEAD (3.0.2+)
79 seconds by RedCloth 2.0.11.
...there is a lot more than just RedCloth.to_html happening
in the import, so RedCloth portion itself must be more than 2 times faster.
