I'm a bit confused. You need static pages, because you can't handle the load, but you want perl to power it all?
Yes, as in Perl will generate those static pages once in a while, from templates that I create. Therefore, Perl will be powering it.

Your low load option is to just use static pages. Very little processor load, because serving static pages it the easiest method of web serving.
Exactly, is that I'm doing it with a twist. Static pages will be generated by Perl scripts.

Spiders can index results from CGIs, but can't generate the parameters passed to CGIs that you may want.
Either I'm misunderstanding you, or you're simply incorrect. Search engines won't spider:
http://www.foo.com/foo.cgi?whatever=300 but they would spider:
http://www.foo.com/foo.cgi
