It's instructive to run ./python Modules/_decimal/tests/bench.py (Hit Ctrl-C after the first cdecimal result, 5 repetitions or so).
fastint2.patch speeds up floats enormously and slows down decimal by 6%.
fastint_alt.patch slows down float *and* decimal (5% or so).
Overall the status quo isn't that bad, but I concede that float benchmarks like that are useful for PR.
