[Haskell-cafe] Shootout favouring C

[Daniel Fischer]

Hi,

Is it only my machime, or can you confirm that for the Ackermann benchmark, 
it's very good for C that they chose 9 and not a larger value? For 10, we are 
significantly faster and for 11,12,13, we can run rings around the 
C-programme:
dafis at linux:~/Documents/haskell/shootout> time ./cacker3 10; time ./acker 10; 
time ./cacker3 11; time ./acker 11; time ./cacker3 12; time ./acker 12
Ack(3,10): 8189

real    0m0.664s
user    0m0.660s
