Hi We are using prefork apache on Red Hat Enterprise Linux AS 4 with the following settings: MaxKeepAliveRequests 100 KeepAliveTimeout 15 <IfModule prefork.c> StartServers 8 MinSpareServers 8 MaxSpareServers 300 ServerLimit 575 MaxClients 575 MaxRequestsPerChild 4000 What I am unclear about is that if the server limit is 575 and I have actually reached this limit will there be 8 additional children started(MinSpareServers) that is not serving requests but will be if any of the other children stops or reaches MaxRequestsPerChild? When I do a character count on server-status I get the value of 584 which confirms my above reasoning. This apache httpd server is used to front 12 Tomcat servers using mod_jk. I think the MaxSpareServers value is a bit high. I believe the original reasoning behind this value has been because we receive regular burst of traffic and then it is better to have apache keep the processes active to sit out the burst of traffic. We have also considered changing the parameters as follows to improve performance after a httpd restart which unfortunately at the moment is fairly often: StartServers 16 MinSpareServers 16 MaxSpareServers 64 Any opinions on these values would be appreciated.
