23800 RAR3-p (Compressed) performance problem

[Campomeister]

I'll look into as much as possible, because I don't have such a powerful machine. Can you reproduce the same behavior also with a single 4090?

Thank you for the response! Using the command 

Code:

./hashcat.bin -d 1 -w 4 -m 23800 -a 3 example23800.hash "?a?a?a?a?a?a"

I get ~26kH/s per RTX 4090, which is similar to the cumulative speed from the second demo.
The low usage GPU, high usage IO uninterruptible CPU periods are now shorter (4 periods in 5-6 minutes)

If you need the full demo in asciinema, I can record it.
