I have heard mixed reports on whether there is a speed difference.

What is certain is that if you convert CGI to mod_perl using the
classic Apache::Registry, what you get is slower than PHP.  But if
you code explicit handlers in Perl, the gap at least narrows
significantly, and memory use improves.

With Ruby I predict the same holds.  Additionally for CGI, people
who use << to incrementally build strings are likely to get
significantly better performance than those who create large
numbers of small objects, or who do unneeded copying with +=.

What it really comes down to is this, "Is it fast enough for you,
and is it maintainable in its current form?"

Cheers,
