在我的windows机器上git stash
每次调用的开销大约为3.5秒,这为我的git commit钩子增加了大约7秒。git暗藏在窗口上很慢
在linux(同一台机器)下的相同命令大约需要0.01秒。性能问题也适用于空存储库。
我试图从this thread和this thread如下:
core.fscache
设置为true
core.preloadindex
设置为true
gc.auto
设置为256
- 设置PS1 = '$'
- 在管理中运行cmd N模式
- 内CMD.EXE而不是混帐bash的运行
运行GIT_TRACE=true git stash list

从日志中我们看到,它需要大约git-stash命令之间运行3秒,并运行git-rev-parse。有没有其他的标志可以用来找到瓶颈?
这可能是你的仓库很大,你可以尝试在你的本地和远程仓库上启动'git gc'吗? – Flows
它在一个空的存储库中花费相同的时间量。我已经更新了这个问题。 – sighol
