Massive slow performance from 900 GH/s to 37 MH/s

You should probably start by using a version of hashcat that isnt 4 years old. After you update to a more recent version of hashcat and retest, make sure that whatever command you are running doesn't include --force. Once you've got both of those figured out, then you can worry about adding more work or restructuring your attack to achieve a proper workload and better speeds.
