Visual Studio 2017中的Git速度非常慢

我做了一些基本的检查，比如在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，切换分支只需几秒钟，而不是一分钟。我们注意到慢速PC上的网络流量大得多

当我在安全模式下运行Visual Studio时

devenv.exe /SafeMode

我立即在团队资源管理器中看到以下错误：

如上所述，我尝试的第一件事是：

devenv.exe /updateConfiguration

但这并没有解决问题。然后我跑：

devenv.exe /setup

它给出以下错误消息：

无法完成该操作。请求的操作需要 海拔高度

我在日志中看到的错误有：

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.

我以管理员的身份运行VisualStudio。问题仍然存在，但在以后以用户身份以安全模式运行时，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修复也没有修复该问题。我正在使用VisualStudio15.6.5

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.

有许多类似的错误：

日志显示在Git和VS之间切换。磁盘操作本身很快，但在Git.exe文件关闭后

C:\Program Files（x86）\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\mingw32\bin\Git.exe

关闭几乎需要一秒钟的时间。在git.exe发生QueryNameInformationFile事件几乎一秒钟后，它在

C:\Windows\System32\conhost.exe

上关闭了文件

当没有什么特别的事情发生的时候，我拍摄了线鲨。我看到我的电脑和公司代理webdefence.cluster-x.websense.net之间的流量很大。流量比我的同事多得多，他们没有看到错误

当使用有线、无线或在家使用VPN连接时，问题仍然存在

我怀疑这是NTFS权限的问题

我试着跑，但没有用

Tweaking.com-也无法修复文件权限。

这可能是联想L460-e-ID阅读器i7 SSD的硬件问题

系统重新启动。证监会发现了一些错误，可以修复。Wireshark的流量看起来正常，但问题依然存在。首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，不可能在第一分钟内显示新网页。网站持续加载很长时间。

删除此目录中的“Git”文件夹，然后重新启动VS

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

该文件夹覆盖了正常的Git执行

PS：如果您使用的不是“社区”版本，请进行相应修改。

（1）使用stanfalone git切换分支是否也很慢（2）在长分支切换过程中进程树是什么样子的，哪个进程（如果有）消耗CPU。问得好。我已经安装了Ortoisegit，但还没有测试它。没有问题：切换分支不到4秒。没有CPU消耗弹出。尽管如此，一些进程需要很多时间才能完成。也许它会在一些网络呼叫中等待。因此，请发现共享流程树的相关部分在这里并不是最佳选择，因为它使用了另一个实现。windows cli的标准git会更好。windows CMD的git也可以正常工作。似乎删除此文件夹只会强制VS使用系统上默认安装的git。所以在我的情况下，它一开始很有帮助，直到我更新到git版本2.23。更新之后，一切又开始缓慢地工作。恢复到2.22版完全解决了这个问题。
