Own stripped down version of FontAwesome, or a global cache?

[Squazz]

I’ve been looking into how I can optimize my loading of font-awesome. As per the below linked post, it seems that “everybody” is using the global cache.

Reduce FontAwesome Load Time

Dear All I use WordPress with FontAwesome installed (built in) form theme. I’ve optimized my site and the score is good enough in PageSpeed, Pingdom, GTmetrix, etc. But the only slowing my site now is FontAwesome. The FontAwesome size is about 75kb but the load time is almost 2 seconds just for loading FontAwesome only. The source of my FontAwesome is like this → mydomain.com/wp-content/themes/annina/fonts/fontawesome-webfont.woff2?v=4.7.0 I set no query string on the cache setting page, th…

The obvious gain with this approach, is that I could hope that visitors to my site have already visited a site that’s using te global cache, and therefore won’t spend time downloading the same file again as it’s in the browsers cache.

Klternatively I should make my own kit from font-awesome, and only include the CSS that I actually need. This is what I do at the moment. and it “saves” me 30Kb of CSS (for font-awesome 4.7.0)

I can’t figure out what would be the best approach. To use the global cache / CDN, or to create my own package only containing exactly what I need for my Wordpress theme.
