HELP WITH GPU SPEED

[Snoopy]

you could run a benchmark to see the "theoretically" max hash/s per card for this hashmode and compare it with your output (add -D2 when needed)

hashcat -b -m22000

jfyi the speed of plain wordlist is always slower, you can combine your wordlist with rules to take some advantages of the gpus

i think it drops to 0 when hashcat copies a new bulk of candidates to the gpu ram, so dont worry
