Am I doing something wrong to cause this poor performance?

Not sure why your performance dropped. What version are you running -- latest release, or beta? You might try the latest beta, and see if you get the same results: https://hashcat.net/beta/

And generally, 11-char ?a is ... ambitious. If you have *any* idea of what the characters might be, even if you did get 1M/s, I'd reduce the character set. 11 chars of ?a is going to take longer than you might expect.

Thanks for the response royce. I'm running cudaHashcat-2.01. I changed it to use: -1 ?l?d?u ?1?1?1?1?1?1?1?1?l?l (alphanumeric, both cases). So far it's been running for 2 hours and this is the result:
