How to determine what is causing the load on the site?

Question

CMS

I have a website hosted by SpaceWeb. From time to time, I get a message in my mailbox that my site exceeds the load limit. Although the site has the function of providing information. No services, no processes. Several pages of text, a forum... everything. CMS: WordPress. Template:Adapter. For information: website .

Answer 1

Shared hosting midrange will never be productive. They have limits on the use of resources. At some load, your processor load jumps within acceptable limits, but they go beyond the limits of their system - hence the warnings.
If you debug what exactly causes the load, you need to look at the logs, test with the Plugin Performance Profiler.

Answer 2

Cache everything you can. If the site is self-written - optimize.

Answer 3

If you have access via ssh,
Log in with your credentials (the password field does not change when you enter it, don't be embarrassed. Just type and press Enter),
Execute the commands (just write in the terminal):
sudo apt-get install htop (a great extension for monitoring resources )
htop
You can use the terminal to connect via SSH on Ubuntu and MacOS. On Windows, you need an SSH client. The best one in my opinion is PuTTY
