The issue is almost always the gui, not any package. Input latency in the gui is awful but it's fine in the tui

There's a different read loop? I've not really noticed a difference tbh.

That is not true. There are some features which makes only the GUI version slower, but it's definitely not "almost always" that the GUI is the reason. There are a lot of features/packages which makes Emacs slower in general, no matter GUI/TUI.

So profiling, or bisecting the init file can be used find out the problem.
