## Reduce time to first byte

In addition to the amount of time it takes for your page to fully load, you’ll also want to take a look at the amount of time it takes to start loading.

Time to first byte, or TTFB, is the amount of time a browser has to wait before getting its first byte of data from the server. Google [recommends](https://developers.google.com/speed/docs/insights/Server
) a TTFB of less than 200 ms. 

Here’s a snapshot of the 'timings' tab that gets shown when a response file on the network tab of devtools is clicked. It shows a website that has an excessive TTFB.
