did you try redirecting output to a file? on freebsd and linux it runs a
much faster if it's not outputting to the horribly slow console.
if you want something really fast, check out 4brute-johnbs (4brute with bitslice des code from john the ripper)...
it does 1211kcps on my 1.6GHz turion laptop (running freebsd amd64, using the 128-bit sse2 assembly code from jtr)...
