PDF mode 10500 slow

[PWn3R]

run
hashcat -b -m 10500
and see output, this would be the "perfect" speed you can get with this hashalgorithm

EDIT: running with 2 1050ti

Hashmode: 10500 - PDF 1.4 - 1.6 (Acrobat 5 - 8) (Iterations: 70)

Speed.#1.........:  3144.8 kH/s (91.85ms) @ Accel:1024 Loops:70 Thr:64 Vec:1
Speed.#2.........:  3158.0 kH/s (85.43ms) @ Accel:1024 Loops:70 Thr:64 Vec:1
Speed.#3.........:  473.1 kH/s (79.57ms) @ Accel:32 Loops:70 Thr:64 Vec:4
Speed.#4.........:  380.9 kH/s (73.34ms) @ Accel:32 Loops:70 Thr:64 Vec:4
Speed.#*.........:  7156.7 kH/s

so your 
Speed.#1.........: 71570.6 kH/s (33.21ms) @ Accel:512 Loops:70 Thr:64 Vec:1
seems quite okay, 10 times faster

Thanks, so this algorithm is just slow. All good.
