So I'm messing with Puzzle #130 and JLP's Pollard Kangaroo ECDLP Solver using a RTX 2070. When I first launch it, this is the speed I get:
[1553.87 MK/s][GPU 1459.12 MK/s]
After a few seconds running at that speed it will slowly decrease until it reaches this speed, where it stays for the rest of the operation:
[1209.19 MK/s][GPU 1134.42 MK/s]
Does anyone know why this is happening?
Thanks in advance!

Because statistics are wrong until all threads loads kangaroos. Wait about 10-15 seconds to get right numbers.
