How to identify the reason for the slow loading of posts through ajax?

Question

Google Chrome

Hello!

The site has ajax load more. On mobile resolution, the speed of loading posts is not satisfied. I just come across work on optimizing the site and am a little unfamiliar with the depths of testing. How can you analyze and find out what the problem is? does it take a long time to process an ajax request (in this case, disable the plugin responsible for this and write the loading manually) or is it just a page that takes a long time to load and, having worked on optimization, will reduce the speed of loading posts?

Chrome has a built in profiler. In addition, you can open the "network" tab and see if the response from the server is fast. (and most likely this is the problem, at least I would start checking from here).
