And uphill both ways! But according to this test, printing one header by hand is 11331% more efficient than using CGI to do it. Did I miss something?

Yes, you missed something. Two things in fact - "bottleneck" and "profiled". I didn't say I'd benchmarked lots of individual lines of web-apps - I said I'd profiled lots of web-apps! When you profile you find out where the important things to tune are - the really slow things that actually matter. Things like database access, file access, search algorithms, etc. NOT things like CGI.pm!

Benchmarking is a useful tool but it's nearly useless as a way to figure out what's worth spending time optimizing. If you find yourself wanting to disagree then I suggest you stop programming in Perl immediately - C is so much faster! Just try benchmarking:

  for (0 .. 100000) { $a++; }

Versus:

  for (int x = 0; x <= 100000; x++) { a++ }
