It says to use a multiplexer for tabs and splits, but doesn't that negate some of the performance claims?

Tmux and screen are pretty notorious for slowing things down.

I use window manager for tabs as it should be. No need for some stinky multiplexer.

I think it's unfair to label tmux "stinky".

It is slower, that's true, but so many times I've had to restart my terminal or I've quit it accidentally and tmux has saved my bacon.

Performance is adequate (for me), it's cross platform and gives me multiple cut/copy buffers.

Oh that’s very interesting to hear about tmux increasing latency. I’ve not heard this before but now you mention it, it seems obvious. Could you elaborate?

Terminals emulators aren't aware of tmux panes, so it'd likely needs to redraw the whole thing if even a single pane changes.

Tmux scans every character at least once.
