[Haskell-cafe] Vedr: To my boss: The code is cool, but it is about 100 times slower than the old one...

[Fixie Fixie]

That's really an argument for upgrading to 7.4.2 :-)

Another reason for doing things with haskell is this mailing list.

Thanks!

Felix

On 7.4.2:

$ time ./c_test
...

real    0m0.145s
user    0m0.040s
sys    0m0.003s

$ time ./Test
...

real    0m0.234s
user    0m0.220s
sys    0m0.006s

Both compiled with -O2.
