可见:


Max Requests
Per Child: 256 - Keep Alive: off - Max Per Connection: 100


【


该apache限制为每个子进程可以处理256次请求，每个线程最大连接数为100


进程数的最大值由MaxClients控制，在Apache1.3中最大只能设置为256，但在Apache2.0中，可以通过在配置开头增加ServerLimit项目来突破256的限制，此时必须MaxClients ≤ ServerLimit ≤ 20000


MaxRequestsPerChild用来控制每个进程在处理了多少次请求之后自动销毁


Keep Alive: off


】

8.


可见:


Timeouts
Connection: 20 - Keep-Alive: 5


【


MaxVhostClients  100 


Keep-Alive: 5 这个应该没意义，因为Keep Alive: off


】
