Apache（XAMPP）在高負載時沒有響應

Question

我的電腦有8個內核和16GB內存，在高流量的情況下，當RAM達到3GB時，我的web服務器（apache-xampp）無法訪問。我的CPU只用於20％。我需要重新啓動Web服務器。

我設置php.ini中上

max_execution_time=60 
memory_limit=10128M 

有任何建議，以優化我的服務器，讓我的服務器可以爲至RAM/CPU使用到它的極限？

一些調整的，你可以添加到您的Apache配置文件（httpd.conf）是

KeepAlive On 

MaxKeepAliveRequests 75 

KeepAliveTimeout 100 

AcceptFilter http none 
AcceptFilter https none
