可以使用以下参数配置Apache的并发连接数: <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 MaxClients 150 MaxRequestsPerChild 1000 </IfModule> <IfModule worker.c> StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_winnt.c> ThreadsPerChild 250 MaxRequestsPerChild 0 </IfModule> 对于Windows系统,缺省会使用mpm_winnt,配置中有用的是第三段,即: <IfModule mpm_winnt.c> ThreadsPerChild 250 MaxRequestsPerChild 0 </IfModule> 具体含义可参考Apache的官方文档: http://httpd.apache.org/docs/2.2/mod/mpm_common.html#threadsperchild
