Then you really should use rainbowcrack, or ophcrack 
(http://lasecwww.epfl.ch/~oechslin/projects/ophcrack/) which comes 
bundled with a rainbow table.

If you feel inclined to have a time/memory tradeoff, you should have an 
efficient one.

And if you really want to calculate hashes, i suggest you use something 
like a quick'n'dirty perl script, that will be slower but all in all i 
think it will save you a lot of time.
