Dictionary cache building

[Mem5]

Hi,

Using last stable hashcat version with my GTX 1080, each time I launch a LM attack it builds the cache :

Code:

hashcat64.exe  -w 3  -o  lm_res.txt --potfile-disable  --gpu-temp-retain=75 -m 3000 hash.txt words.txt

Gives :

Code:

Dictionary cache building xxx.dic: 1140817173 bytes (4.03%)

I though it was just the first time ? It does it each time I launch LM attack, then MD5, then LM again.
Is the Dictionary Cache Building the same for every algorithms or different for LM ? That would explain why it needs to be rebuilt for LM.

Thanks.
