Cloudflare, even the free tier, improves my site speed and security – so much so that I use it for all my sites. The default settings boost site speed by global distributed caching of static content. Static content, by Cloudflare’s definition, excludes HTML. This makes sense for dynamic sites with frequent new posts and user comments. For my sites like this one, that have less frequent new posts and do not allow user comments or other dynamic content, I can dramatically increase site speed using a page rule.
