TTFB or Time to First Byte is the hardest thing to optimize in WordPress. This guide will help you with implementing some easy steps to improve TTFB

What is TTFB?

Time to First Byte. As the name suggests, it’s the time required to receive the first byte from the server, or inessential how fast your receive data when requesting a webpage

TTFB vs Loading Time

Sometimes TTFB is confused with loading time of a website. However, they’re not the same. Loading time refers to the total time of a request which includes sending, TTFB, downloading, parsing, etc.

How to Measure TTFB?

There are several tools to measure the TTFB. My favourite one is because it will do the test from 14 locations

What is Good TTFB?

Google recommends having a TTFB of maximum 200ms. Even 200-400ms is ok. Anything beyond 500ms is considered slow. It will clearly affect the whole speed of the website and user experience

With the follows steps, you can easily achieve less than 70ms!

How to Reduce TTFB in WordPress?

Use Cloudflare DNS

DNS has a vital role in page speed and TTFB. It is how your browser finds your server and connects to it. Faster your browser connects to the server, faster TTFB!

Here is a comparison on the response time of Cloudflare DNS with popular services

ProviderResponse Time (lower is better)
Cloudflare12 ms
GoDaddy48 ms
Route 53 (AWS)49 ms
Google Cloud59 ms

Use TLS 1.3

TLS is the successor of SSL. It’s a protocol to provide end-to-end encryption (HTTPS). TLS 1.3 is the latest version. Version 1.3 reduces the number of round trips and provide a significant improvement in TTFB

It requires only a few changes in the server, but you could reduce up to 250ms just by upgrading to TLS 1.3

Choose Server Location Wisely

If your audience is in India and your server is in the US, that will add an extra 200-300 ms network latency

Select your server location wisely. Choose the server that is very close to your audience location. Most of the cloud hosting providers like Cloudways, Kinsta has locations all around the world

Cache HTML Pages on CDN

An HTML page is the first piece your browser asks when a user visits your website. Due to several factors, Cloudflare by default won’t cache HTML/JSON. However, you can write custom rules to cache HTML pages in their CDN servers. This will increase the TTFB by 10x or even more!

Use a Cache Plugin

For every new request to a page, WordPress has to execute PHP and MySQL queries. But 90% of the time you don’t need it. You can generate HTML files and serve them directly. It’s very fast when compared to generating it from PHP

There are several plugins that help you to enable cache in WordPress. My favourite one is WP Rocket

Use a VPS/ Managed Hosting

Unlike shared hosting, VPS/Managed hosting providers don’t share resources across other sites. What this means for you is a faster website

Not every VPS or managed hosting providers are good. My favourite ones are Cloudways and Kinsta

Use PHP v7.3

Which version of PHP are you using? Is it 7.0 or 7.1 or 7.2? If so you should definitely upgrade to PHP v7.3

If caching or static website isn’t a good solution (especially for e-commerce, forums) then speeding up processing the only way. It’s not just about increasing CPU and RAM

Even though it’s a smaller upgrade in the number, the performance is notably different!

Use Cloudflare Argo

Argo detect real-time congestion and route web traffic across the fastest and most reliable network paths


Cloudflare powers 10% of the internet! They know which is the fasted path to deliver. With Cloudflare Argo, you can speed up the TTFB by 35%

Argo isn’t free, unlike the above services. It costs $5.00/month + $0.10 per additional gigabyte

Convert to Static Website & Use Static Hosting

What is a Static Website?

If your WordPress site not very dynamic, you can create a static version of it. A static version is a site that contains only HTML, CSS, JS, images etc. Not PHP or MySQL. A landing page for a company/product, blogs, etc are good examples of static sites

What is Static Hosting?

Static hosting providers like Netlify are designed for high-performance delivery of static files. It comes with built-in CDN, including HTML.

Creating Static version of WordPress and deploying

Install WP2Static plugin which will generate the static website. Then connect Netlify as the hosting provider (I’ll write a detailed tutorial for this)

Enjoy super-fast static sites!


The first impression is the best impression. TTFB is more important than your total website load time. I hope the above steps will help you to decrease the TTFB
