Why is xterm not included? It’s probably the most popular terminal on Linux. It’s also noticeably laggy. I’m surprised that eshell performance is so good. Maybe because it supports less features than a standard terminal? I use Emacs and Elisp everyday and both are dog slow. It’s unfortunate that they still haven’t managed to replace the interpreter and bytecode compiler with a faster scheme compiler after all this time. As an aside, GNU projects seem broken in their management. Every project seems to be run by some get off my lawn egomaniac. (ex RMS, Ulrich Drepper)

(ex RMS, Ulrich Drepper) The list of projects currently run by that list of people comprises "emacs and nothing else." Drepper left glibc maintainership many years ago and RMS has not been actively involved in anything other than emacs for a similar duration (aside from crippling gcc backend splitting).

  Doesn't X11 ship with macOS (i.e. to run "legacy" Unix apps)? I could've sworn I've used xterm before on it.

    It doesn't ship on it anymore. It used to a number of years ago.

    No, but you can install it: https://www.xquartz.org/ https://www.xquartz.org/

  Doesn't XQuartz come with xterm?

  There are Linux tests in that benchmark. Moreover, you can run xterm on OSX.

I would assume that this is caused by emacs having some pretty complex logic to minimize screen updates to absolute minimum in order to support slow serial links to text terminals which is presumably also used in graphical modes.
