Wpa/Wpa2 dictionary attack is very slow after the latest update

[Virgula]

EDIT:

Code:

hashcat -m 2500 net.hccapx /dict -w 3 --session different

Speed.Dev.#2.....: 3345 H/s (74.82ms) @ Accel:16 Loops:8 Thr:512 Vec:1
Speed.Dev.#3.....: 4717 H/s (49.27ms) @ Accel:32 Loops:16 Thr:1024 Vec:1
Speed.Dev.#*.....: 8062 H/s

But my computer now lags a little and before not and the speed was 16.000 H/s not 8.000!.... I don't understand... maybe problem is due to latest Osx o.s updates...
