Keyhunt does not take long to load, it takes a long time because you do not save the files.
If you add the -S command, your next run will take a very short time.
I did take that into account.
Even with the -S parameter it takes more than one minute to load in with my machine.
In my particular case almost 2 minutes to initialize Keyhunt, 20 seconds for BSGS-CUDA.
