I get 2KH/s on a hash attack vs more than 100KH/s on the benchmark. They're both running in the same mode -m 11600 -D 2

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.

This hash-mode is known to emit multiple valid candidates for the same hash.

Use --keep-guessing to continue attack after finding the first crack.

Cracking performance lower than expected?                 



* Append -w 3 to the commandline.

  This can cause your screen to lag.



* Append -S to the commandline.

  This has a drastic speed impact but can be better for specific attacks.

  Typical scenarios are a small wordlist but a large ruleset.



* Update your backend API runtime / driver the right way:

* Create more work items to make use of your parallelization power:

As a side note, I didn't manage to use the Metal API. Trying -d 1 or -d 2 returns "No devices found/left".
The 7zip encryption mechanism has a variable "cost". The benchmark runs against a hash with a cost of 2^14 (16384 iterations), where your file has a cost of 2^19 (524,288 iterations).
