I have less. Only 5 Ekeys/s, which is very little.
He should be taught not to slow down if there are a lot of keys.
By the way, I modified the divider from Alberto ecctools.
I made a subtractor out of it, and it saves everything into a text file. It can also take keys line by line from a file and take them away in order and write them either to a given file, or it creates a file with the name of who it subtractor it from and writes the keys.
