When working on powerful remote machine over RDP (XRDP) I could see that it become laggy and xrdp consumes CPU. After some back and forth, I've assumed it may be to high refresh rate and it seems to be so - once I've set rps to 5, xrdp CPU consumption became much lower.

As well, when working over ssh - which is a quite standard thing too, having high FPS doesn't make much sense, i.e. over 250-300 ms link, what kind of FPS/RPS you may expect :)

I've build local package, enabled debug information ( Ctrl+P -> Toggle Debug ) , watched FPS is limited while producing some output. In the other terminal, I was watching top for xrdp.

"classical" situation:

Its your lucky day! I just opened a PR to do just this because I was annoyed my CPU fan was too loud. :D You can check it out here:
