First of all this isnt meant to be accurate or very reliable, even flawed, I just want to see some numbers, because in pymuxs README, it mentions about the performance, but not actual numbers:
Tmux is written in C, which is obviously faster than Python. This is noticeable when applications generate a lot of output. Where tmux is able to give fast real-time output for, for instance find / or yes, pymux will process the output slightly slower, and in this case render the output only a few times per second to the terminal. Usually, this should not be an issue. If it is, Pypy should provide a significant speedup.

I use my own test script, termfps.sh, which is written in Bash. I thought about using find or yes as mentioned in the README, but I am too lazy to write a script for the tests, I used what I already have in hand.
Since pymux is written in Python, so I tested with two implementations, the official CPython and PyPy (RPython to C). They will all run within the environment virtualenv creates, and using pip to install pymux 0.5 and Pyte 0.4.10, and along with their dependencies.
The test script is run with reset && ./termfps.sh in urxvtc with font xft:Envy Code R:style=Regular:size=20:antialias in dwm with virtually full-screen of 1680x1050, dwm topbar is hidden, and the window size is 1669x1027 and geometry is 111x33.
Both tmux and pymux are run without configuration files.
