我在运行 Apache 2.2 的 Windows 2003 Server 中遇到了问题。
服务器的性能似乎真的很差，作为测试，仅仅尝试加载 10kb 的文件就需要一段时间才能在浏览器中加载。
有人有提高性能的建议吗？
我的 httpd.conf 有以下设置：
KeepAlive On
MaxKeepAliveRequests 500
MaxRequestsPerChild 0
KeepAliveTimeout 4
Timeout 60
HostnameLookups off
以及 /extras/httpd-mpm.conf

# identification number when it starts.
#
# Note that this is the default PidFile for most MPMs.

PidFile "logs/httpd.pid"

答案1
请在 httpd.conf 中查找以下指令并取消注释它们：
EnableMMAP off
EnableSendfile off
还可以在 httpd-mpm.conf 中设置此项
<IfModule mpm_winnt_module>
ThreadsPerChild 32
MaxRequestsPerChild 10000
Win32DisableAcceptEx
</IfModule>
