Introduction

Before we start with the speed up of WP, we will show you how to measure the speed of loading the first byte of web or TTFB (time to first byte) + page response time. This happent at the client’s end after the request is processed at your server and the first content is sent. That’s the reason why this value is so important without the actual web content.

Measurement

We use three ways how to measure TTFB + page response time

1) Using the pingdom.com service

pingdom_add_1
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0  1270    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
HTTP/1.1 200 OK

real	0m0.270s
user	0m0.031s
sys		0m0.011s

3) Using the developer tools in your browser

Developer_Tools

With these three options you can measure the speed of your WP website anytime during the speed optimization.

1. Choose the good web hosting provider or build your own simple server infrastructure

Definitely don’t choose the cheap hosting. Those hostings are usually overexposed and use the older infrastructures. So rather try to build up your own infrastructure.

Or we recommend to use the hosting optimized for WordPress:

Flywheel (starting at 15$/mo per 1 wordpress install)

WPEngine (most popular WP hosting, but cost 29$/mo)

2. DB Optimizing and caching

Optimization of the database is another key element in speeding up the website. For example backup of all article revisions may fill up the thousands of rows in the database and slow it down. We recommend to use the free wp-optimize plugin to optimize the database.

… and the next most important step is to turn on the caching. Page cache module can speed up your page response time more than 200%. We recommend this free plugin:

banner-772x250

3. Using a CDN

Use of CDN will not even shorten the load time of your website for all countries but will protect the server against the DDoS attacks, minify your CSS, JS, HTML files and save you up to 60% of your traffic. Ideally use it together in combination with caching plugin w3 total cache. This plugin can also connect the MaxCDN service with your WordPress back-end

We recommend these worldwide largest CDN services:

MaxCDN (you can connect this CDN with WordPress W3 total cache)

CloudFlare

Conclusion

Thats all:)

Below is the screenshot from our measurement of one our project using the pingdom service. Time to first response of the page was 1400ms a went down to 350ms.
