How to Reduce Server Response Time and TTFB in Wordpress

pattern 21

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 to start loading. You can test your TTFB quickly with Bytecheck or test simulating a real user TTFB metric with WebPageTest.

For the full picture and past field data of your website TTFB, use Treo.

Below are the best ways to improve the web vital TTFB metric and reduce the server response time in Wordpress.

Use 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/month, and it caches the HTML of your WordPress website. This is possible due to Cloudflare Workers that cache dynamic content.

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

Upgrade your hosting

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.

Use a CDN

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