init.el vs init.org
All changes to the configuration should be done in init.org, not in
init.el.
This is what the initial init.el should look like.
(require 'org)
(find-file (concat (getenv "HOME") "/.dots/files/emacs/.emacs.d/init.org"))
(org-babel-tangle)
(load-file (concat (getenv "HOME") "/.emacs.d/init.el"))Startup
lexical-binding can improve speed.
;;; -*- lexical-binding: t -*-Tangle
The init.el should (after the first run) mirror the source blocks in
the init.org. We can use C-c C-v t to run org-babel-tangle, which
extracts the code blocks from the current file into a source-specific
file (in this case a .el-file).
To avoid doing this each time a change is made we can add a function to
the after-save-hook ensuring to always tangle and byte-compile the
org-document after changes.
(defun tangle-init ()
(when (equal (buffer-file-name)
(expand-file-name (concat (getenv "HOME") "/.dots/files/emacs/.emacs.d/init.org")))
;; Avoid running hooks when tangling.
(let ((prog-mode-hook nil))
(org-babel-tangle))))
(add-hook 'after-save-hook 'tangle-init)Performance for start-up
A common optimization is to temporarily disable garbage collection during
initialization. Here, we set the gc-cons-threshold to a ridiculously large
number, and restore the default value after initialization.

Performance
lsp-mode
Some optimization for lsp-mode
(setq read-process-output-max (* 3 1024 1024))Scrolling
Disable bidirectional text scanning for a modest performance boost. I've set
this to nil in the past, but the bidi-display-reordering's docs say that
is an undefined state and suggest this to be just as good:
(setq-default bidi-display-reordering 'left-to-right
bidi-paragraph-direction 'left-to-right)
Disabling the BPA makes redisplay faster, but might produce incorrect display
reordering of bidirectional text with embedded parentheses and other bracket
characters whose paired-bracket Unicode property is non-nil.
Emacs 27+ only.

Built-in DocView isn't too nice to use.
pdf-tools offers smoother scrolling and a nicer search.
isearch-forward-regexp replaces swiper in this mode, as swiper would regexp in the PDF source.
Keybinds:
C-s: search, just as inswiperC-s(again): forward searchC-r: backward search
