I have Cygwin's git (2.21.0) and Git for Windows (2.21.0) installed on
my Windows 10 machine. I run the following command with each binary
"git push --all" on a simple 2 line change to 1 file. If I use Cygwin's
git, then the operation takes almost 5 minutes. If I use Git for
Windows, then the operation takes almost 20 seconds. I tried using
--verbose to figure out why Cygwin's git is so slow but it does not
reveal anything to me as to why. What can I do to figure out why
Cygwin's git is so slow? I am hoping that we can get to the bottom of
this and it can be fixed to help all users.
You might try turning on GIT_TRACE_PERFORMANCE [1] and see if that
shows any differences.
If you can install 2.22.0-rc* versions of both, you can turn on
GIT_TR2_PERF [2] and some additional details.
If your repo is very large, it may be due to some Windows file system
optimizations present in the Git for Windows version.
