till now i thought that for speed tests under linux "gcc -O6" is the
reference. I recently compared some language implementation suitable for
www-programming (the old fibonacci function with argument 30).

Surprise surprise!!!

Olabl bytecode (caml + objects + labeled and optional arguments) was
only 30% slower than JAVA JIT COMPILED code and only 5 times slower than
optimized gcc code.

Olabl native (i386) compiled code was TWICE AS FAST as "gcc -O6"
compiled code.

Ram consumtion is only constant (200k) larger than with the gcc program.
Olabl seems to have a larger minimal runtime (not only the already
loaded libc.so.xx) environment.

Maybe this observation cannot be generalized but it fits to the very
good impression i have from almost all the INRIA stuff ..
