I have just recompiled my BlurFit routine under OcamlOpt 2.02. This version
is a completely new and far more sophisticated version than the one I
developed in December in only 3 days. However, its timing is still dominated
by large numeric array operations, and I would expect no increase in
performce for those inner tight loops.
The non-numeric overhead has been measured at 0.28 sec/iteration under
OCamlOpt 2.01 and 0.6 sec/iteration for the numeric operations.
Under OcamlOpt 2.02 the same program executes in 0.85 sec/iteration, for an
apparent speedup of roughly 10% in the non-numeric OCAML overhead code.
I think this is very good indeed. But I am posting this for the benefit of
the developers who may be interested in how their changes affect real-life
programs. I would be interested to hear from others regarding the speed
improvements.
