高負荷時にApache（XAMPP）が応答しない

Question

コンピュータに8コアと16 GBのRAMがあります。トラフィックが多い場合、RAMが3GBに達したときにWebサーバー（apache-xampp）にアクセスできません。私のCPUは20％しか使用していません。そして私はWebサーバーを再起動する必要があります。それに使用されるRAM/CPUが限界だまで私のサーバーがサービスを提供できるように

私はphp.iniの

max_execution_time=60 
memory_limit=10128M 

でこれを設定するには、私のサーバーを最適化するための任意の提案は、ありますか？

あなたがApacheの設定ファイル（httpd.conf）に追加することができます微調整の一部

KeepAlive On 

MaxKeepAliveRequests 75 

KeepAliveTimeout 100 

AcceptFilter http none 
AcceptFilter https none
