In your config: <IfModule prefork.c> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> # worker MPM # StartServers: initial number of server processes to start # MaxClients: maximum number of simultaneous client connections # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # ThreadsPerChild: constant number of worker threads in each server process # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule worker.c> StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> # perchild MPM # NumServers: constant number of server processes # StartThreads: initial number of worker threads in each server process # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # MaxThreadsPerChild: maximum number of worker threads in each server process # MaxRequestsPerChild: maximum number of connections per server process <IfModule perchild.c> NumServers 5 StartThreads 5 MinSpareThreads 5 MaxSpareThreads 10 MaxThreadsPerChild 20 MaxRequestsPerChild 0 </IfModule> That, in my opinion, is an insane amount of spare threads to have. Do you really need 25-75 spare threads for your workers? --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
