Git 在 Windows 10 上慢得无法使用

Question

I have a Windows 10 laptop with SSD, 16GB of RAM, and an i7 processor.

I have read this thread and none of the solutions helped. Git/Bash is extremely slow in Windows 7 x64

I have tried using Git in the following scenarios:

1. Command Prompt
2. Git Bash Shell
3. Visual Studio 2015
4. Source Tree

All of them are pretty much unusable. For example, before I started typing this question I ran the following command from the Command Prompt:

git flow feature start "Separate_Cash_Incentives"

It has been running for over 10 minutes and has not completed yet.

When I look at my task manager, my CPU is at 10%, my memory is at 40%, and my disk is at 5%.

There are currently 10 "Git for Windows" processes running and all of them say 0% CPU.

How can I fix this problem?

Thanks!

EDIT: It appears that the majority of the slowness happens when creating or merging branches. Just doing a simple commit or push is pretty fast.

Just for testing, try and

Try and:

• unzip PortableGit-2.12.2.2-64-bit.7z.exe (if you have a Windows 64 bits) anywhere you want.
  For instance: C:\\git\\2.12.2.2

• open a regular CMD console and set a PATH to:

   set PATH=C:\\WINDOWS\\system32;C:\\WINDOWS;C:\\WINDOWS\\System32\\Wbem;C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\ set PATH=%PATH%;C:\\git\\2.12.2.2\\bin;C:\\git\\2.12.2.2\\cmd;C:\\git\\2.12.2.2\\usr\\bin;C:\\git\\2.12.2.2\\mingw64\\bin

Then type bash -l -i and see if Git is still slow.

The goal is to make sure you don't have any conflicts with other software in your PATH .

Also, try and (for testing) turn out that your anti-virus to see if there is any side-effect here.

Finally, make sure your codebase is on your local drive (not accessed through the network or shared mounted folder)

It remains to be tested if a simple exception rule (for instance on the git installation folder) would be enough for git to run normally (ie, if the AV is set to not check its git installation folder).

It appears that the majority of the slowness happens when creating or merging branches.

Speaking of merge, Git 2.28 (Q3 2020) will include some code optimization for a common case.

See commit 8777616 (19 May 2020) by Andrew Ng ( andrewyng ) .

merge : optimization to skip evaluate_result for single strategy

^{Signed-off-by: Andrew Ng}

For a merge with a single strategy, the result of evaluate_result() is effectively not used and therefore is not needed, so avoid altogether.

On Windows, this optimization can halve the time required to perform a recursive merge of a single commit with the LLVM repo.

您可以在完全卸载后尝试重新安装 git，然后尝试在 git bash 中运行这些命令。
