Comparison
Here is a result from GTmetrix to show you the changes between before and after. (Same web server located in Tokyo, Japan, vultr.com)
- Remove query strings from static resources - let all the proxies could cache resources well. (https://gtmetrix.com/remove-query-strings-from-static-resources.html)
- Make fewer HTTP requests - through combined the loaded js files into the one.
- Prefer asynchronous resources - change the css delivery method using a script block instead of link tag.
- And TODOs ...
