Visual Studio 2017中的Git非常慢

Question

我做了基本的检查，比如没有网络驱动器上的文件夹，更改某些git配置设置，使用不同的repo，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，只需几秒钟即可切换分支，而不是一分钟。我们注意到慢 PC上有更多的网络流量。

当我以安全模式运行Visual Studio时，

devenv.exe /SafeMode

我立即在团队资源管理器中看到以下错误：

System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
   at Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(Int32 hr, Int32[] expectedHRFailure)

   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的建议，我尝试的第一件事就是：

devenv.exe /updateConfiguration

但这并没有解决问题。然后我跑了：

devenv.exe /setup

它给出以下错误消息：

  

无法完成操作。请求的操作需要   标高。

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.

我以管理员身份运行Visual Studio。问题仍然存在，但我在以后的安全模式下以用户身份运行时，日志中不再有任何错误行。

我在常规启动时看到一个错误和许多警告：

ERROR Encountered an ArgumentException when trying to look up the key binding information for ({ef254ccf-cee3-43e9-a22c-3ae3ab08e7fe},256) in the scope {5efc7975-14bc-11cf-9b2b-00aa00573819}.

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

我运行了sfc来检查Windows系统文件。

sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For

supported in offline servicing scenarios.

有很多这样的错误：

CSI    000010f2 [DIRSD OWNER WARNING] Directory [l:48 ml:49]'\??\C:\Program Files\Windows Identity Foundation' is not owned but specifies SDDL in component c2wtsres, arch amd64, nonSxS, pkt {l:8 b:31bf3856ad364e35}

Process Monitor日志显示Git和VS之间的切换。磁盘操作本身很快，但是在git.exe FileCloses C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\mingw32\bin\git.exe之后，它在关闭C:\Windows之前几乎只需要一秒钟。在git.exe的QueryNameInformationFile事件后几乎一秒钟，它在C:\Windows\System32\conhost.exe上执行CloseFile。

当没有什么特别的事情发生时，我做了Wireshark捕获。我看到我的PC和webdefence.cluster-x.websense.net（公司代理）之间有很多流量。流量特别高于我的同事，他们没有看到错误。

使用有线，无线或在家中使用VPN连接时问题保持不变。

我怀疑这是NTFS权限的问题吗？

我尝试运行SFCFix无济于事。

Answer 1

这可能是此Lenovo L460 - e-ID reader i7 SSD中的硬件问题。

系统重新开始。证监会发现了一些错误并可以修复它们。 Wireshark的流量看起来很正常，但问题仍然存在。第一次登录系统的同事也有同样的问题。

我注意到的另一件事是当Opera浏览器启动时，在第一分钟内无法显示新的网页。该网站的加载时间很长。

Answer 2

删除此目录中的“ Git”文件夹，然后重新启动VS

C：\ Program Files（x86）\ Microsoft Visual Studio \ 2017 \ Community \ Common7 \ IDE \ CommonExtensions \ Microsoft \ TeamFoundation \ Team Explorer

该文件夹将覆盖您正常的Git执行。

PS：如果使用的不是“ Community”版本，则进行相应修改。 干杯
