将apache2的最高性能设置为70％ - 80％

Question

我尝试在apache2.conf上编辑它

<IfModule mpm_prefork_module>
    StartServers          8
    MinSpareServers       8
    MaxSpareServers      15
    ServerLimit        2000
    MaxClients         2000
    MaxRequestsPerChild   0
</IfModule>

StartServers和MinSpareServers从5到8
MaxSpareServers从10到15
ServerLimit和MaxClients从默认为2000。

我的网站2000上的平均用户在线（我看到的最大值是3100）

我需要让3100用户在线保持我的网站平稳运行，并获得最佳性能。使用70-85％可用的RAM。

谢谢你们
