modify PHP-FPM config customization

[taker18]

I have 64G ram Server 8 core, but my but i have one of my site is very large and heavy, and all the times the admin site is extremely sluggish

this is my PHP-FPM config customization

./data/users/admin/php/php-fpm83.conf​

1. 
   
2. [admin]
3. user = $pool
4. group = $pool
5. listen = /usr/local/php83/sockets/$pool.sock
6. listen.owner = $pool
7. listen.group = apache
8. listen.mode = 660
9. pm = ondemand
10. pm.max_children = 10
11. pm.process_idle_timeout = 20
12. pm.max_requests = 500
    
    
    Now I am convinced that I shouldn't switch pm = Ondemand to Dynamic, it should stay the same as Ondemand ok fine.
    but what about the rest
    
    pm.max_children = 10
    pm.process_idle_timeout = 20
    pm.max_requests = 500
    
    in fact some recommendation to add
    pm.max_children = 60
    pm.start_servers = 6
    pm.min_spare_servers = 4
    pm.max_spare_servers = 10
    
    
    any recommendation I want to change pm.max_children = 60 (increase it more than the default 10)
    Thank you

Check your php-log is it asking to raise children count? because your TOP shows there no load at all

the admin site is extremely sluggish

That can be caused by a bunch of reasons. You might enable slow logs in PHP-FPM and see what is causing issues. Common reasons:

1. too slow SQL queries
2. requests to remote services, sites
3. operations with images (re-sizing, converting, etc)
