Yamiraan

I have a good server
AMD Ryzen 5 3600
RAM32 GB DDR4
Storage480 GB NVMe
and hosting 15 wordpress websites only few website have traffic ( 100 to 200 users online)
issue is my server always overload, when i edit/delete any post/category CPU start consuming 100% and also Server consuming high level server sources,
any expert can help me please? im willing to pay for this, tried 3 freelancers but they just tune the server but my issues are still there, and at last they said this is website code issue not server issue,
If some guru help me i also can reinstall server but really need some expert who can find out real issue

Yamiraan Hello, first of all I think WordPress is a very good website source code, its code is very good robustness, so I do not think it is a code problem. Of course if you use a third party theme, it may cause your server resources to be 100% when editing and deleting as you said, of course your server configuration is also very good. If I can, I am willing to try to help you see what is taking up the server's resources, email:bt_dapao@qq.com

First, you must break down the 100% CPU usage. Using #top command you will see which PROCESS consume certain % usage.
I suggest you reinstall your server then install Proxmox, so you can divide/break-down any SUSPECTED process by using Container. Also 200 users x 15 WP = 3.000 users online? So you may take a look at: MySQL - Current Status. Usually the WP problem come from Database Server.

Yamiraan may be you need to check your plugins list as always WP consumes cpu or ram with plugins
you need to check what is cpu eating either sql or php on that base you can optimize

is a website code issue, not a server issue
99% it's a wp plugin or theme.
you need to enabled/disable/test each of them to see the hungry CPU script

Don't waste your time, I've faced the same issue by having just 2 WordPress sites.
No matter what you do, your CPU will reach 100% on every single request.
Most WP themes/plugins are very badly optimized. The only way to make it work fine is using a clean WP install with nothing more than few plugins
It's not about aaPanel since I'm hosting some sites with more than 10k users online at the same time and barely reach 50% of CPU usage.
Avoid a headache and move your WP sites to a shared WP hosting.

True! use the minimum of plugins

200 users online at a time is way too high for that dedicated server you have made. And 15 website of 100+ users is still very high traffic. I believe you are paying 35euro for that spec as I do have one. So consider upgrading your server to 100 euro one from the same provider which is of 5900x CPU and it can handle a bit. If it still did not work, you have to split the website into multiple servers.

I have this every day:

And nobody can´t help with this... Jose not implementing cgroup or anything to detect what eat resources... It´s dead end.

this is not busy time and server is smooth when i captured this image

Yamiraan those php-fpm commands are basically the requests done on your WP sites. It can be some user accessing or even crawlers trying to index your site.
Please note that if CPU reaches 100% all your sites will be frozen until some CPU is available.
If you insist on using WP on your server, I recommend disabling all site themes/plugins and activating 1 by 1 until finding which one is raising your CPU usage. In my case was the Avada theme.
Also, consider brute force attacks which is pretty common in WP, so take in mind that those numbers will be highly increased if any of your sites is a BF target.

Use HTOP to see what site use these resources, example:

But this not work with MySQL big usage and for others...
