;;; Commentary:
;; Emacs HEAD (27+) introduces early-init.el, which is run before init.el,
;; before package and UI initialization happens.

;; Defer garbage collection further back in the startup process
(setq gc-cons-threshold most-positive-fixnum)

;; GCC Emacs deferred compilation.
(setq comp-speed 2
      comp-deferred-compilation nil)

;; Using straight.el means we don't want to initialize package.el at all.
(setq package-enable-at-startup nil)

;; By disabling UI elements during early-init we prevent the glimpse of un-styled Emacs.

;; Resizing the Emacs frame can be a terribly expensive part of changing the
;; font. By inhibiting this, we easily halve startup times with fonts that are
;; larger than the system default.

;; Ignore X resources; its settings would be redundant with the other settings
;; in this file and can conflict with later config (particularly where the
;; cursor color is concerned).
