Tests by my SEO specialist (who copied my site to a dedicated server) showed that I could shave 2s off my page load times by a) moving Webflow's built in JavaScript to load at the end of my pages (file example is 201.4 KiB https://uploads-ssl.webflow.com/5a05c214d7919e0001b5bb9e/js/webflow.ec5ad0111.js), and b) moving from a shared to a dedicated server.

Moving the JavaScript did not appear to affect functionality.
