我需要更改TCP InitialCongestionWindow的默认值
我看了这个文件：
https://www.iispeed.com/blog/windows-server-2012-and-tcp-slow-start
我在我们的hyper-v托管虚拟服务器2012 R2上尝试了它.
PS C:\>Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionProvider CTCP
我收到了错误：
Set-NetTCPSetting : No MSFT_NetTCPSetting objects found with property 'SettingName' equal to 'Custom'. Verify the valu
e of the property and retry.
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (Custom:String) [Set-NetTCPSetting],CimJobException
+ FullyQualifiedErrorId : CmdletizationQuery_NotFound_SettingName,Set-NetTCPSetting
问题是如何才能完成IISspeed文档所说的内容？如果我在Hyper-v机器上更改此功能我是否还需要在hypers-v主机上更改此功能以实际上有所不同？
我是否应该对SSL端口443进行相同的更改？
我运行了这个命令：

您需要首先创建传输过滤器,它将TCP设置指定为NetTcpSetting对象,如下例所示.
原文链接：https://www.f2er.com/windows/367867.htmlNew-NetTransportFilter -SettingName Custom -LocalPortStart 80 -LocalPortEnd 80 -RemotePortStart 0 -RemotePortEnd 65535
当您要修改设置时,将使用Set-NetTCPSetting命令行开关.因此,为什么您收到有关未找到的自定义对象的错误.创建传输过滤器后,您的原始命令可以修改设置.
Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionProvider CTCP
