As opposed to not using anything? Yes. They are much faster than what people usually write on their own though. > If there is effectively perl code in the template which actually > changes with different pages that load, isn't mod_perl forced to > recompile the code for each request? There are different pages for different templates, but once they have been compiled they don't need to be loaded again. See my templating article for more on how this works. > When I looked at all this a while back, I figured that this must be > the case, and went with CGI::FastTemplate as it uses pure regex > matching, I suspected it was likely to avoid this.

They don't have to parse the template at all after the first request in each process. Of course they have their own sources of overhead, but template parsing is not one of them. - Perrin
