I've been looking for methods to improve Emacs performance especially with my configuration being over >3k. I'm not particularly interested in startup-time since I never close Emacs. Here's what I found so far

(setq package-native-compile                            t
      gcmh-high-cons-threshold                          100000000
      gc-cons-threshold                                 100000000
      scroll-conservatively                             101
      jit-lock-defer-time                               0
      large-file-warning-threshold                      nil)



(add-hook 'after-init-hook #'(lambda () (setq gc-cons-threshold (* 100 1000 1000))))
(defvar gc-timer nil)
(defun salih/maybe-gc ()
  (let ((original gc-cons-threshold))
    (setq gc-cons-threshold 800000)
    (setq gc-cons-threshold original
          gc-timer (run-with-timer 2 nil #'salih/schedule-maybe-gc))))

(defun salih/schedule-maybe-gc ()
  (setq gc-timer (run-with-idle-timer 2 nil #'salih/maybe-gc)))

(salih/schedule-maybe-gc)

I can tell that I've noticed some improvements.

With the new --init-directory switch of Emacs 29, you can define a completely separate environment for Emacs that could be used to make more mean, lean and specialized versions of Emacs. For example, instead of having your Emacs do everything, IRC, email, programming, Org mode stuff etc. etc. etc. you could have a shell command invoking each one, e.g. Eirc, Eemail, Eorg, etc.
