我需要更改TCP InitialCongestionWindow的默认值
我读了这个文件： https ： //www.iispeed.com/blog/windows-server-2012-and-tcp-slow-start
我在我们的hyper-v托pipe的虚拟服务器2012 R2上试用了它。
PS C:\>Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionProvider CTCP 我得到错误：
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 + Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionPro ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (Custom:String) [Set-NetTCPSetting], CimJobException + FullyQualifiedErrorId : CmdletizationQuery_NotFound_SettingName,Set-NetTCPSetting
问题是我怎样才能实现IISspeed文档讲述的内容？ 如果我在Hyper-V机器上更改这个我是否也需要在超级主机-v主机上改变这个以实际上有所作为？
我是否也应该对SSL端口443进行相同的更改？
我运行这个命令：

您需要首先创build传输筛选器，将TCP设置指定为NetTcpSetting对象，如下例所示。
New-NetTransportFilter -SettingName Custom -LocalPortStart 80 -LocalPortEnd 80 -RemotePortStart 0 -RemotePortEnd 65535
Set-NetTCPSetting命令行使用当你想修改一个设置。 因此，为什么你收到有关未find自定义对象的错误。 创build传输filter后，您的原始命令来修改设置应该工作。
Set-NetTCPSetting -SettingName Custom -InitialCongestionWindow 10 -CongestionProvider CTCP
嗨我运行时得到相同的错误：
PS C:\Windows\system32> Get-NetTransportFilter SettingName : Automatic Protocol : TCP LocalPortStart : 0 LocalPortEnd : 65535 RemotePortStart : 0 RemotePortEnd : 65535 DestinationPrefix : * SettingName : DatacenterCustom Protocol : TCP LocalPortStart : 80 LocalPortEnd : 80 RemotePortStart : 0 RemotePortEnd : 65535 DestinationPrefix : *
换句话说，已经有一个端口80（ DataCenterCustom ）filter和另一个其他端口（ 自动 ），由于某种原因，我没有权限编辑（我是一个域networking的一部分，我不是在主节点中）。
我所做的是更改Set-NetTCPSettingfilter的名称运行第二部分：
Set-NetTCPSetting -SettingName DatacenterCustom -InitialCongestionWindow 10 -CongestionProvider CTCP
那就是全部，现在是Works
