I am making a social networking website with PHP, MySQL, Javascript, JQUERY, and AJAX. I have setInterval and setTimeout function to show messages, friend requests etc every second with ajax. But I see that it is sending a response every second and finish time to increase continuously. Will it affect my server performance?

Please see the snapshot -

Inspect website shows increasing finish time continuously

    That time is simply the difference between the time the page started to load and the last request made. So you can load a page that loads within 500 milliseconds, does nothing else (no request), and 10 minutes later fire off a fetch() request and that time would then read 10 minutes.

The finish time logs all on-going requests even after the page has loaded (e.g. AJAX). So whenever you click a button that brings new data in the website, the finish time is extended.

If you want to monitor the initial page load time, use the load time just to the right. Here is a comparison between the two: https://stackoverflow.com/a/31304442/2026428

  • So it means it won't overload the server?
