2.4.1.19. Site technical check
Site technical check allows you to check server response time and a number of other general points. You can run the check in the "Site technical check" section.
Server response time check
Detailed information about what server response time (TTFB) is can be found here.
To start the check for the first time, click "Create files and check server response time" in the "Server response time check" section.
To check the server response time, two files will be created in the site root directory: a file with a PHP extension that outputs plain text using echo, and a text file with a TXT extension. During the check, the server response time is measured when accessing the site's home page and the two created files. As a result, you will get three server response time indicators — when the site is fully operational, when scripts are running minimally, and when static content is being served.
The results of the check look like this:
By calculating the difference between the time for the main page and the time for the PHP file, you can find out the approximate time it takes for the site's scripts to run.
