Copy and reuse dictionary cache

[fa1rid]

Alright, explanation:

Let's say I have 20GB dictionary file and hashcat cat needs 5 mins to cache it in the beginning of the attack.

Now if I split the file into 5 parts (20/5=4) so it's 4GB each file. This way I'm expecting hashcat to load the cache 5x faster (in 1 min all of them) because instead of using 1 core it should use 5 cores and in parallel cache all the 5 files at the same time together, but this is not happening, instead it loads the first file and does the attack, then load the second and does the attack and so on.

Thanks!
