coming right up
(different parameters, different machine, best of 5 -- it varies quite a
lot)
time (ocamlbuild -clean; ocamlbuild facs_run.native)
4.03.0 1.36s
4.03.0+flambda
Oclassic 1.68s
O2 2.1s
O3 2.80s
the actual run: time ./facs_run.native
4.03.0 23.3s
4.03.0+flambda
Oclassic 24.2s
O2 22.7s
O3 20.1s
so it seems compilation on flambda classic is still a bit slower than
non-flambda; as is the run time. the gains of O3 over non-flambda are
still significant, as is the difference O2 vs O3.
