hi everybody I've got a new dedicated server with 48go/ram, with a fresh installation of debian wheezy + apache2 + php + mysql + postfix + pure ftpd + ispconfig3. I should use this server for some websites hosting. (about 10)(prestashop+wordpress) here is my (default) apache2.conf setting : <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> I'd like to change it for optimization, do you have any advice please ? thank you
