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.
