How many hashes are you cracking, what hash type, and on what OS?
There's a new version I'm getting close to releasing that is somewhat faster, but is still limited to a single GPU.
I plan to rewrite it soon to support multiple GPUs & CPU cores at once.
If you are using a GTX series card and can handle very slow display updates while it is running, try adding:
--threads 512 --blocks 512 -m 500
That should help performance.
