Arcane Emacs

Fiddling around with my Emacs configuration tonight, I discovered that the way I specify my default frame font can (paradoxically) have a big impact on my Emacs startup time.

I was picking my font using:

(set-face-attribute 'default nil
                        :family "Fira Code"
                        :height 120)

Which I kinda thought was prohibitively slow. After a little bit of deep Googling, I found another way, namely

(add-to-list 'default-frame-alist '(font . "Fira Code-12"))

This shaves about 0.45 secs off the start-up time.

Why? I have no idea…
