Using CDNs to Unlock a Big WordPress Speed Boost

Alex Denning / September 20, 2016 Hey! I’m Alex Denning and seven years ago I founded WPShout. I passed the site to Fred and David when I started university, who have done wonderful work since. I’m now freelancing full time and producing a course for WordPress users to become WordPress masters. Today’s post is an excerpt from the course. Enjoy!
A fast website is important. 47% of people expect a site to load in less than two seconds and 4/10 of your visitors will abandon your site if it takes more than three seconds to load. One usability study (that is dated, but the theory remains legitimate) suggests users will tolerate a small delay, but will be equally unsatisfied with a medium delay as a long delay.
You might not think of your site as “slow”, but even if it takes a bit of time to load visitors may perceive it the same way as they would an exceptionally slow site.
There’s a way of avoiding visitors leaving because your site is slow: have a really fast site.
One of the biggest hurdles you’ll face when trying to make your site faster is images and other static files such as JS and CSS. Images especially can be large files and slow to load
