Speed comparison WPA/WPA2 (2500) vs WPA/WPA2 PMK (2501)

[ZerBea]

Speed depend on count of hashes inside the hash file and/or nonce-error-correction value. How have you measured the 20%?

I can't reproduce such a big difference running an example hash from here:
https://hashcat.net/misc/example_hashes/hashcat.hccapx

one EAPOL hccapx:
real 0m9,860s
user 0m3,913s
sys 0m4,207s

versus

one EAPOL 22000 (the same as in the hccapx file)
real 0m9,389s
user 0m3,939s
sys 0m3,686s

As expected, the measured values are nearly the same

envirnonment:
$ uname -r
5.5.10-arch1-1

$ pacman -Q | grep nvidia
nvidia 440.64-5
nvidia-settings 440.64-1
nvidia-utils 440.64-2
opencl-nvidia 440.64-2

$ pacman -Q | grep cuda
cuda 10.2.89-3

in detail (disabled automatic nonce error corrections, to make sure we have the same conditions):

Please post your complete comparison,
$ time hashcat -m 2500 + your options
versus
$ time hashcat -m 22000 + your options
to find out what is going wrong.
