Recommended server configuration

[JohnnyTWA]

Hello,

I wanted to ask the community if they have a recommended server setup/configuration for Apache/php-fpm/FFI/VIPS.

At the moment the server has 2 cores and 8GB of RAM but we're finding that php-fpm instances sit in the background taking up RAM and CPU long after the processes finish, eventually the server sits at nearly 100% CPU.

Changing from Imagemagick to VIPS has been the only change.

php-fpm config is
dynamic mode,
max_children 64
min_spare_servers 5
max_spare_servers 64
start_servers 8
max_requests 25

Any advice would be greatly appreciated.
