How to Improve TTFB and Speed up WordPress Website

Last updated on April 29, 2022 | By

Time to First Byte (TTFB) is the time your server takes to make the request to your page load. It has a lot of technicalities as to what goes into all the requests for the page starting load, but you can test your TTFB with Bytecheck or WebPageTest.

Since TTFB is a server and backend matter, you could consider optimizing these two. Take a look below for top tips to improve your TTFB.

Cloudflare DNS

Setup Cloudflare on your domain to leverage Cloudflare DNS and get your response time slower. Cloudflare setup requires changing your domain DNS records.

Cloudflare APO

Cloudflare Automatic Optimization is a new tool to improve WordPress TTFB. Cloudflare made a study and concluded that APO optimized their WordPress client’s websites TTFB for a 72% improvement.

Not only that, but their clients FCP(First Content Paint) and Speed Index had an improvement of 22% and 13% respectively. Cloudflare APO setup requires changing your domain DNS records.

Cloudflare currently offers Automatic Platform Optimizations (APO) for 5$/mo, and it caches the HTML of your WordPress website. This is possible due to Cloudflare Workers that cache dynamic content.

“Automatic Platform Optimization consistently demonstrated better aggregate performance among sites we analyzed in TTFB, First Paint, FCP, and LCP metrics. Even more impressive are improvements on both desktop and phone form factors.”

Cloudflare APO is compatible(you need to manually purge Cloudflare APO cache) with WP Rocket and many other plugins, check the compatibility here.

Consider a better hosting or upgrade plan

Quickly check if your site has a bad TTFB using Bytecheck or WebPageTest. An ideal TTFB metric is the loading below 300ms, with 300ms to 500ms considered slow. Above 500ms is very slow.

You don’t necessarily need to move from your hosting, you can simply test by buying a plan with better hardware, memory, or CPU.


CDN alleviates your server requests by loading from a specific server meant to deliver static assets. Consider the following CDN for your WordPress:
