How to increase the speed of 23800 mode?

[zxc583700871]

Just look at this line

* Hash-Mode 23800 (RAR3-p (Compressed)) [Iterations: 262144]

the magical word here is Iterations, to check for one candidate the hashalgorithm needs to be calculated over 250k times

so in fact your "normal" speed for one iteration would be 300 * 262144  = 78.643.200 hashes per second but due to iterations its slows massivly down

there is nothing you can do about it

for faster loading, you could try splitting up your wordlist into smaller chunks, put them into one directory and feed this directory as input

I tried splitting the dictionary file into smaller files, each containing 200,000 lines. Loading each file takes approximately 1 minute, yet the actual GPU computation ran for less than 2 seconds.
Then I rented a machine equipped with 3080x4 GPUs, and it took less than 1 second for each dictionary to be loaded and for GPU computations to finish.
