Expected hashrates with -m 22000

If you GPU is consistently showing 100% utilization, you're supplying enough work for the GPUs to not be bored. For a slower hash like the WPA family, speeds like you're showing aren't unreasonable, but there may be a little more room for more speed.

With a straight wordlist, I get ~350kS/s on GTX 1080s, but the GPUs aren't consistently at 100%. Supplying a small rules file like best64.rule gets me ~430kH/s and consistent 100% usage.
