Need to find the reasons for the slow loading of the site?

Question

PHP

Hello toaster! There is one site that loads very slowly.
I ran some tests that might tell you something. Tell me where else to look for the problem.
A WordPress site with 43 different plugins activated in total.
The server is located in the Netherlands.
Displayed the number of queries to the database and the time spent on their execution.

156 queries in 2,739 seconds.

File upload speed
Files that are uploaded from outside
Result YSlow

Answer 1

start from here
https://wordpress.org/plugins/jetpack/
and
wordpressinside.ru/plugins/wordpress-caching
throw out that tester, use www.webpagetest.org
watch how the second site load loads

Answer 2

Lib.js 20kb in 1 minute. On the ISS, the flow goes faster.
Comprehensive:
https://wordpress.org/plugins/wp-minify/ this one, or look for something similar.
+ caching headers or manifest (yes, there are plugins)
Another option is CDN cloudfare or clones. more expensive, but solves the problem immediately

Answer 3

43!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 4

People have spawned "smart" js libraries, plugins - and it slows down. As they say - you have to pay for everything)
1) Make the pictures sprites.
2) Fewer plugins =)
3) Less fancy fonts
Remove in general what is essentially not needed.

Answer 5

Most likely slowing down WordPress itself. Set up caching.

Answer 6

I would start with lib.js which takes 80 seconds to load. The rest just pales in front of him) It is
very strange that a file of this size is loaded so much. I take it it's local?

Answer 7

Well, except for the standard settings (leaning into one file, minification, client-side caching, other optimizations recommended for WP). Set up everything on the server. (optimize slow queries, enable memcashed)
