Wordpress site high cpu usage

[MediaStar]

Hello all, i need help here.

My site using CPU up to 2xxx%, right now i need to enable CF under attack mode and cpu usage down to 20%~30% only.

Spec:
-AMD Ryzen Threadripper 2950X
-8x RAM 16384 MB DDR4
-Litespeed Enterprise

Also already disabled all plugin, still same.

After enable under attack mode:

Not sure this is because of database problem or attack?

Anyone know how to fix these?

Seems DDOS attack.

Just to know, do you have the Burst Statistics plugin, if so, your problem may come from there. Otherwise, it is indeed a ddos attack.

This is my list of plugin, how to check more deep related with ddos from Cloudflare?

close the plugin one by one and see if stops.

Yes solution available
Use redirect plugin
Change your main domain and redirect to new domain
With time frame 2 to 3 second
Problem will solve
Thank you

The load is generated from php index.php, use a caching plugin so it doesnt have to compile the page every load.

W3 Total Cache

Search Engine (SEO) & Performance Optimization (WPO) via caching. Integrated caching: CDN, Page, Minify, Object, Fragment, Database support.

wordpress.org

If not using cloudflare check images,css,js have correct headers set for caching.

if you don't have any cache plugin, could make the cpu use high.

After rename admin-ajax.php, my site cannot play the video because page required ajax.

Already use Litespeed cache plugin.
