True about mod_perl. Haven't messed with that myself, either. fork/exec really is very cheap on Linux, so it's not a huge deal.
In the case of Perl scripts, it's not really the fork/exec overhead, but the Perl startup overhead that you want to try to optimize. But given your later statement (lots of spare cpu), this ends up just being a bit of a latency hit. In general, I think mod_perl has a much bigger impact when you have a database to connect to at startup. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
