Hi Simon
Benchmarks please! Let's see some comparisons on the nofib suite. If
there's a
factor of 2 or less between GHC -O2 and YHC for any of the nofib
programs, I'll
eat my keyboard for lunch :-)
http://www.cse.unsw.edu.au/~dons/nobench/bench.results
Test: pidigits (lazy, arbitrary precision integers)
http://www.cse.unsw.edu.au/~dons/code/nobench/imaginary/pidigits
ghc 3.200 seconds (1.0 x)
ghci 3.500 seconds (1.1 x)
ghc-old 3.600 seconds (1.1 x)
yhc 5.740 seconds (1.8 x)
Would you like ketchup with that? ;)
pidigits is not (currently) one of the nofib programs (phew :-). I suppose the
reason for the results is because the test spends most of its time in GMP?
There are some other odd results in nobench, like the 2 programs where Hugs
beats GHC that we need to look into.
Cheers,
Simon
