RE: Performance tuning/improvements

  I implemented a "mail rendering" engine based on velocity a
while ago. With quite sophisticated velocity-templates and
a lot of other procession stuff I managed to generate over
a million mails / hour (including all the javax.mail - stuff,
so, a "ready-to-send" email!) on a P4 2GHz desktop. And that was
*without* caching. Have you done any performance test by now?

  Nevertheless, looking for performance improvements is never
wrong! :)
