i'm sorry that my comment is off the topic of web development...

A few months ago, I ran the Fibonacci test for gcc 2.95 and ocamlopt
on the Intel platform and saw the similar result; I was not interested
in PIC at the moment.  First, I thought the difference was due to
inlining done by the ocamlopt but it was not the case for Fibonacci
function.  Comparison of the assembly code produced by the both
compiler suggests that the difference is due primariry to the fact
that gcc does not optimize enough argument passing to functions.
