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.
I’ve focused on what I really need and avoid cluttering my config. I’ve spent considerable time understanding what performs well and what doesn’t. I try to minimize the use of global modes and refrain from installing additional packages if built-in ones do the job. I’m very discerning when it comes to choosing any new package. Essentially, I have to “sell” myself on a new package, if you know what I mean. Yes, I do use byte-compilation for Lisp code and feel that I’ve managed to make things quite efficient and clean. You can take a look and borrow any solutions from my setup here: https://github.com/sergeyklay/.emacs.d
