Hello lag, my old friend
(alien.top)
A community for the timeless and infinitely powerful editor. Want to see what Emacs is capable of?!
So stop sighing and start profiling.
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 can be profiled, too
Please. What is profiling?

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.
