Having a hard time figuring the exact "math" around the apache2-mpm-itk configuration option MaxClientsVhost
We are running one front-end server with nginx, and are proxying traffic to our two back-end servers running Apache with apache2-mpm-itk.
Each Vhost is now running as its own instance so they won't affect each other. However, if a Vhost has a set limit of MaxClientsVhost 250, does this mean that we in theory have a max capacity of 500 visitors at any one time?
If so, how long does a visitor remain a visitor, until that one spot is once again freed for the next?
I also remember tinkering with the maximum connection properties for apache before, and I seem to remember that the values set her, we're affected by each other with something like how many connection per apache sub-worker or something. Is this also the case for apache2-mpm-itk?
Does these values affect the MaxClientsVhost in any way?
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
