If we use -r flag for re-key and we set it to let's say 1M, does that mean program will use random base key every 1M keys? Would that work with higher speeds? When I try to use -r and I set it up to 1M then I get max speed of 35MK/s (uncompressed). Probably that is maximum that it can calculate when you use very low re-key number for base key.
