| For non-threaded servers (i.e., prefork), MaxClients translates into the maximum number of child processes that will be launched to serve requests. The default value is 256; to increase it, you must also raise ServerLimit. this and ServerLimit should be the same or very close with MaxClients never exceeding ServerLimit. For servers under high load this value should be increased. See below for more information on how to define the maxclients directive. | For non-threaded servers (i.e., prefork), MaxClients translates into the maximum number of child processes that will be launched to serve requests.

| A simple calculation for MaxClients would be: (Total Memory – Critical Services Memory) / Size Per Apache process. I define Critical Services as services such as mySQL, Plesk, DirectAdmin; any service that is required for proper operation of your server. | A simple calculation for MaxClients would be: (Total Memory – Critical Services Memory) / Size Per Apache process.
