我在本地的WAMP服务器上进行开发，有时候我会滥用数千个ApacheBench [ab]请求。 然而，默认情况下，似乎apache扼stream器，然后closures后，我的并发水平传递200秒的请求（当基准的东西）。
在Windows上，你如何让更多的连接（如400RPS）？
C:\>ab.exe -n 3000 -c 400 http://localhost ：编辑：
看来httpd-mpm.conf文件包含答案。 但我不知道应该更改什么设置，甚至是Apache运行的模块。

解决方法是取消注释httpd.conf中的MPM config include
# Server-pool management (MPM specific) Include conf/extra/httpd-mpm.conf
然后findmpm_winnt_module并将线程数从250改为任何。
<IfModule mpm_winnt_module> ThreadsPerChild 1000 MaxRequestsPerChild 0 </IfModule>
要检查你的configuration状态，添加mod_status.so模块。
<location /server-status> SetHandler server-status Order Deny,Allow Deny from all Allow from all </location>
然后检查http：// domain / server-status，find工作线程，调整你的configuration。
