Relation between apache processes/Threads and HCO configuration

  • 1.  Relation between apache processes/Threads and HCO configuration

    Hi,

    I'm trying to define the correct settings for the HCO MaxSocketsPerPort parameter.
    I let the default value of 20 and checking the number of connections I found 70 connections.
    I'm using an apache in MPM worker mode.

    I verified I have 5 httpd processes currently running and only 1 LLAWP.

    I read that apache in this configuration is able to open 1 connections for each thread.
    Is the MaxSocketsPerPort limit applied at process level?

    which are the parameters in apache I have to check for understand the maximum number of connections I can reach?

    I guess ThreadsperChild to have the maximum number of threads per process
    (if this value is set to 30 and MaxSocketsPerPort is set to 20, how many connections I can open for this process?) 
    ServerLimit for the maximum number of processes
    ThreadLimit for the overall maximum number of threads.

    Regards
    Franco
