Attack PMKID 16800 is slow

[miomao]

After I read this thread https://hashcat.net/forum/thread-7717.html, I tried the attack 16800, I have latest version of hashcat git pull few minutes ago, but attack 16800 is slow.
My GPU is not very fast, but I exptect a more fast execution.

Code:

hashcat (v4.2.1-4-g188a9568) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

Is it a normal speed of something is wrong?

[undeath]

That's what you can expect from mid range mobile hardware. Especially the md5/wpa ratio is absolutely normal.

It is still doing the same computation as mode 2500... AKA it still has to calculate the PMK which is very slow.
