Complexity of nginx

Hello,
Would tell me how to reduce the number of spawned php-fpm processes in
order to reduce the load in your server? Results are given below:

Which variables can be optimized to make the server stable. Also,
domains usually have high hits.

So far as above circumstances I ask for your co-operation.

Thank you

With the amount of ram your server have, you shouldn’t reduce your
php-fpm processes. If the server isn’t serving pages fast enough, try
increasing worker processes and php max children.

And your IO wait is rather high; check if there’s any disk problem.
More advanced caching configuration should also help reducing disk
load.
