We are currently using PHP with IIS (until we can get a Linux server)
I haven't found a single post on the internet that has some recommended settings, especially Max Instances and Instance MaxRequests (because I think these are the two most important for performance - unless there are more settings that I missed)
I only found questions where the answers simply copy the text from Microsoft website, for example: https://stackoverflow.com/questions/65637364/how-do-i-configure-iis-10-and-fastcgi-for-high-concurrency
But no post has an actual information on recommended settings. For example - should the Max Instances be as the number of cores? And then what should be Instance MaxRequests? Is there a good ratio between this and Max Instances?
In my case, our server has 8 cores so I set Max Instances to 8, and Instance MaxRequests to an arbitrary value of 800, but maybe I can set it to better settings?
