What’s TTFB?

The Time to First Byte, TTFB, is an indicator that measures the time that the browser should wait to obtain the primary byte of information from the server: it due to this fact determines the responsiveness of an internet server or different community assets.

Find out how to measure the TTFB

Generally, Google PageSpeed ​​Perception recommends response occasions of lower than 200ms so a price that’s at most 100ms is a superb TTFB.

There are a number of instruments to check the TTFB:

  1. Measure TTFB with Google Chrome DevTools

  • Measure TTFB with WebPageTest

The final software we wish to advocate is WebPageTest: you could find the TTFB underneath the heading First Byte Time.

  • Selecting the best supplier

To enhance the TTFB of your WordPress website it is very important select a supplier with a strong and CMS-optimized infrastructure. What components contribute to the success of a terrific infrastructure?

  • Cautious alternative of assets corresponding to RAM, CPU and disk house that assure a performing IT structure

  • Technical recommendation and help

Utilizing a Content material Supply Community (CDN) is helpful for decreasing TTFB.
A CDN is a community infrastructure prolonged globally, with servers positioned on completely different networks that delegate to a CDN the distribution of some components of the positioning, permitting to enhance the TTFB. We use Cloudflare, supported by all our internet hosting plans, included and simply activated.
