Now my problem still is, that I don't know how to speed things up. I

Maybe I need to find a different data structure for my random

lazy lists are simply not working well enough here?
Unfortunately I'm not so good at that myself. Even more
unfortunately, my understanding is that randomly using seq and/or $!
not only usually doesn't help, but can actually make things slower;
and to do it right, you need to refer to the "simplified" Core
Haskell code generated by GHC. And understanding *that* requires
rather more familiarity with Core than I have. :/
