Why is the site slowing down?

Question

Web development

I can't find any reason why go-to-schools.com has such a response time

Answer 1

Video ~ 10 mb. + 130 requests + WP gives the site in 3.68 seconds.

Answer 2

Yes, there is no need to search, you open the developer console and you are horrified at how everything is loaded.

Answer 3

The question should rather be like this:
"Why is the site still loading, I did everything so that it would die. I inserted a huge video into it, and not just 1, but a lot and stuffed it into the slider without a lazyload, loaded 180 scripts, did not combine css files , also put 360000 in the head, so that nothing would work until they are loaded.Jquery 5 versions of different connected and ui to each.I put all the dependencies in the head, there is nothing at the end of the body.And nothing asynchronous.Let everything be loaded before the content.
But most importantly. I never look at the console. I ignore js errors as a matter of principle. And the site still works. What else can I do?"
HZ, I don’t even know what else to advise.

Answer 4

You can optimize js / css with plugins, run images through xnconvert
By the time TTFB - you need to either beat the developer's hands, or put the server more powerful.
