[Haskell-beginners] Speed performance problem on Windows?

[MAN]

A little something I should have done before:

Just compiled Don's C code (modified to my 32 bit laptop) with all
flavors of precision. All the timings were similar:

~$ gcc bigmean.c -o bgC
~$ chmod +x bgC
~$ ./bgC 1000000000
~$ time ./bgC 1000000000
500000000.067109

real	0m8.585s
user	0m8.553s
sys	0m0.000s


So the time's I've been getting are approximating C speed quite well.
There's still the difference between recursive and fusion code that
haven't been able to gap...
