How do you optimise Wordpress v6 under ISPConfig 3 & Nginx?

Hello Friends,
As you know, there are many Wordpress plugin claiming to optimise and cache Wordpress but most of them do conflict with other plugins in certain circumstances.

So can you suggest some skills to optimise and cache Wordpress with the help of the components of ISPConfig v3?

My system is Ubuntu 20.04, ISPConfig v3.2.9.1, Nginx, Wordpress v6.2.

Thanks for your attentions.

 

I have found this from my ebook but where should I put it?

server {
server_name www.example1.com;
location / {
set $memcached_key $uri;
memcached_pass 127.0.0.1:11211;
default_type text/html;
error_page 404 @fallback;
}
location @fallback {
proxy_pass http://backend;
}
}

 

@concept21 did you find a way to optimize your WordPress ?
kindly share if you have any thoughts
Thanks

 

I try "W3 Total Cache".
It will generate some ngnix directives for your reference. Try to choose them for your own use.

I also add these php.ini under my site's option:

PHP:

post_max_size = 128M
upload_max_filesize = 128M
max_input_time = 1000
max_input_vars = 8000
max_execution_time = 300
memory_limit = 256M
