I have developed WP theme for 3 webisites. Both are using pure WP codex code. No frameworks, nothing. The only thing I use is WP bakery PB plugin. But still it is not passing the CLS. I am switching the theme to Twentytwenty or any other default WP theme, turning of all the plugins, but still CLS is going MAD!
For that reason I bought a VPS 12 cores, 16gb RAM. Running CentOS -> CyberPanel with Open Light Speed server, using LS cache, page loading on hover. Nothing helps. Visually the page load is like "light speed" but not for G guy.
Here are the websites that made with the same theme.
The websites almost identical(i mean content but the code and plugins are the same with same versions), but the thing is that on the website number 2 the CLS issue doesn’t exist.
All 3 websites are located on the same server and share all resources.
WP promised on v6.0 to fix the CLS issue, but by then what plugin or code I can use to disable something on WP core to run it faster for the G?
