Last time me and a coworker tried out Zellij (a few weeks ago), there was noticeable input lag compared to tmux. Used the most recent macOS release, running in alacritty w/ zsh. Anyone else had an experience like that? I think for terminal-based tooling like multiplexers, low latency should be a hard requirement.

I've been consistently using zellij for about 6 months now, and i've not experienced any lag. Using iterm2, so not sure if you're seeing alacritty related issues?

Alacritty is faster.

Alacrity may be faster on average, but there might be some bug/edge case/etc that a specific application can hit.

Not input lag but scrolling an editor in fullscreen on a large monitor is kind of laggy for me sometimes. I hope these changes will make a difference (not yet in a stable release).

Of my series of PRs, I suspect the third (i.e. https://github.com/zellij-org/zellij/pull/3043) is most likely to have an effect. But if it does it'd only be as a side effect unfortunately - my focus was on fixing lag with splitting of extremely long lines.

From what I saw while making my changes, that area of the code has a bunch more possible optimisations, but it's 'good enough' for me at this point so I'm not planning to continue pulling at the thread right now. If you wanted to look yourself, I left the script I used for benchmarking and profiling in https://github.com/zellij-org/zellij/issues/2622#issuecommen...
