one thing to note is that the gpu hashcat uses a very complex cacheing, which basically boils down to a buffer per password length, i.e. a buffer for 12 character passwords, a buffer for 13 character passwords, and shoves passwords in accordingly.  Once a password buffer hits a certain threshold, they all get sent to be cracked.  This means you may not get feedback for a certain length try for a while, if it&#x27;s not a common length.  One thing to consider would be to figure out that threshold and keep things internally until you hit it, so you can fill a buffer in one shot.  Realistically, you aren&#x27;t going to get around this very easily, as this buffering is done for performance reasons, in that some of the kernels used rely on same length passwords for performance increases.
