Didn’t know that. Good reason then of course. But I do notice these sort of differences. Codex feels way better than Claude code to me for example.

I tried Toad and to me it feels ridiculously slow and laggy. Switching between input and output (ALT+up/down) for example just lags, I can notice the transition. The whole UI lags. It's no wonder, it's python. Simply the wrong language for this, sorry.

Yeah it feels slow and laggy to me too and I'm not on an old laptop. Running on a M3 Macbook Pro here. I definitely notice the difference between using something like Ghostty (Rust based - super fast) and Toad (Python).

It doesn't really make sense to compare the performance of Ghostty, a terminal emulator, with Toad, a TUI. Also Ghostty is written in Zig, not Rust.

It's obviously way slower though. Also the point stands, it's written in a low-level, performance-oriented language. The author of Toad could have written it in Rust, Zig, C++, etc, but chose Python instead. He valued ease of development versus performance and the result is we get a laggy terminal.

I know for a fact that Textual can generate an entire frame in less than a 60th of a second. Any lag you see has nothing to do with the choice of language. A TUI just doesn’t require that much number crunching to use a low level language.

I’d be interesting in knowing what platform and terminal you observed the lag, when testing Toad.

It is quite literally instantaneous on my 5 year old laptop. Whatever you are seeing isn't due to the choice of Python.

Maybe it's something on my setup then. I notice some delay even though it's by no means huge but noticable. For me these things add up, another example is pane resizing in tmux. I like things snappy, but it's kind of an OCD thing I guess.
