Hi Johan, In you original post ServerLimit was not part of your config, could you just to make sure paste your current config on the list again.
Also make sure you are using prefork and not mpm otherwise different rules will apply in configuring MaxClients and ServerLimit. On a redhat system you can check here: /etc/sysconfig/httpd whether you are using prefork or mpm. We use the default value of MaxRequestsPerChild of 4000. I do not have years of expierence with this parameter but I would stick with the default. I would imagine you only adjust it downwards if you are seeing buggy applications. I am sure someone on the list more knowledgable than me could suggest better reasons to adjust this upwards or downwards Regards > > > > Hi Johan, > > > > > FINALLY, my question is : > > > I would like to allow more machine resources to Apache > to handle > > > more connections and reduce the time to display a page. > > > I reduce the timeout to 45 and : > > > <IfModule prefork.c> > > > StartServers 15 > > > MinSpareServers 10 > > > MaxSpareServers 20 > > > MaxClients 256 > > > MaxRequestsPerChild 0 > > > </IfModule> > > > > > > I tried the put MaxClients = 512 but I have a > message error : > > > WARNING: MaxClients of 512 exceeds ServerLimit value of > > > 256 servers, > > > lowering MaxClients to 256.
