How to Reduce TTFB to Improve WordPress Page Load Times

When it comes to the overall speed of your WordPress site, a lot of times we focus on front-end performance and optimizations to improve page load speeds. However, sometimes it is good to look at it from the server-side, where your website originally starts loading. Today we are going to dive into how TTFB (time to first byte) affects you and discuss some easy ways on how to reduce it. TTFB is commonly an overlooked performance factor, but it should be taken into consideration when testing the speed of your site. What is TTFB?
TTFB stands for time to first byte. To put it simply, this is a measurement of how long the browser has to wait before receiving it’s first byte of data from the server. The longer it takes to get that data, the longer it takes to display your page. A common misconception is that this is calculated after DNS lookup times, however, the original calculation of TTFB in networking always includes network latency. This involves a 3 step process and delays and latency can occur anywhere in between, adding up to your total TTFB.
1. Request to Server
When someone visits your website, the first thing that happens is an HTTP request is sent from the client (browser)
