Here, finally, is a version of libfastmint that incorporates the
work-reduction techniques we discussed earlier. It also builds on
MacOS Carbon/Classic, which it didn't before. Performance should be up
by about 10-15% on all minter cores, usually in the upper end of that
range.
I can now get 3-million per second on my 667MHz 7450, and 3.6-million
on an Athlon-XP 2500+ (slightly faster than the 1600MHz model I was
using before). If I overclocked to slightly over 2GHz, I would break 4
million with that machine.
There's also an "ultracompact" ANSI minter which I hoped would be more
efficient on small-cache CPUs like the M68K series, but it seems that
my "old Mac" compiler produces horridly inefficient code whatever I
try, and I rather doubt GCC (which would doubtless produce better code)
can be coaxed into producing a Classic executable.
At some point I will have to write an assembler routine to do the work
on 68K, as that's where a lot of low-end e-mail users will need it
most. I don't plan to do this immediately, though.
Enjoy!
