How does a CDN speed up WordPress?
Normally your companyWeb hosting WordPress serves your website from a single location. All visitors to your website have access to the same server.
If you have a high traffic website, all of these user requests will slow down your website. During peak traffic hours this can even block the server which will make your website temporarily unavailable.
A study by Strangeloop found that a delay in website speed results in a loss of page more than 11% and a loss in conversion of 7%.
This is where CDN comes in. CDN caches your server's static resources like style sheets, javascript files, and images.
When a user requests your website, all static resources are served through CDN servers. This reduces the load on your hosting server and makes it faster and more efficient.
Static content is served by a network of servers located in different geographical locations around the world. Each user request is handled by the server closest to the user's location. This reduces the page load speed and your website becomes noticeably faster for all users.
