KeepAliveTimeout 15 ## # Server-Pool Size Regulation (MPM specific) ## # Prefork MPM # StartServers: number of server processes to start # MinSpareServers: minimum number of server processes which are kept spare # MaxSpareServers: maximum number of server processes which are kept spare # ServerLimit: maximum value for MaxClients for the lifetime of the server # MaxClients: maximum number of server processes allowed to start # MaxRequestsPerChild: maximum number of requests a server process serves StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 1000 MaxClients 1000 MaxRequestsPerChild 4000
