Git 在 Visual Studio 2017 年非常慢
Git in Visual Studio 2017 is extremely slow
我进行了基本检查，例如网络驱动器上没有文件夹、更改某些 git 配置设置、使用不同的存储库、反病毒扫描等。
到目前为止，我知道问题与我的 Windows 帐户无关。在另一台设备上，切换 b运行ches 只需要几秒钟，而不是一分钟。我们注意到 慢速 PC 上的网络流量增加了很多。
当我运行Visual Studio处于安全模式时，
devenv.exe /SafeMode
我立即在 Team Explorer 中看到以下错误：
System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)

at Microsoft.VisualStudio.TeamFoundation.TeamExplorer.ConnectPage.ConnectPageVS.Initialize(Object sender, PageInitializeEventArgs e)
at Microsoft.TeamFoundation.Controls.WPF.TeamExplorer.Framework.TeamExplorerPageHost.Initialize(TeamExplorerPageContext context)
根据 msdn 上的建议，我首先尝试的是：
devenv.exe /updateConfiguration
但这并没有解决问题。然后我运行:
devenv.exe /setup
它给出了以下错误信息：
The operation could not be completed. The requested operation requires
elevation.
devenv.exe /SafeMode /log D:\temp
我在日志中看到的错误是：
Error loading UI library for package WebEditorPackage. HrLoadNativeUILibrary failed with 0x800a006f.
Error loading UI library for package Microsoft.VsSDK.ExtensibilityProjectFlavor.ExtensibilityProjectFlavorPackage. HrLoadNativeUILibrary failed with 0x800a006f.
Failed to find CTMENU resource '#1000' in loaded UI library.
我 运行 Visual Studio 作为管理员。问题仍然存在，但是当 运行之后以用户身份进入安全模式时，日志中不再有任何错误行。
我在正常启动时看到一个错误和许多警告：

Visual Studio修复也没有解决问题。我正在使用 Visual Studio 15.6.5.

有很多这样的错误：

当没有什么特别的事情发生时，我进行了 Wireshark 捕获。我发现我的 PC 和公司代理 webdefence.cluster-x.websense.net 之间有很多流量。流量比我的同事多，而且他们没有看到错误。
使用有线、无线或在家中使用 VPN 连接时，问题仍然存在。
我怀疑是 NTFS 权限问题？
我试了 运行宁 SFCFix 没用。
