git-lfs track very slow on Windows #5421
Description
Describe the bug
In Windows, git lfs track takes 20+ seconds to execute. I have experienced this issue for some time now. Some few months ago everything was good and I do not know what happened for the problem to show up (I use a corporate computer I do not have full control of). I guess the issue depends on my machine configuration and most likely not everybody can reproduce it.
This delay is very annoying because the HMI I use (Sourcetree) runs the command any time I stage a file.
See #5254
Using export GIT_TRACE=1, I get:

As you see, there is a 23 sec interval between the pos-merge hook installation and the NewLsFiles trace.
To Reproduce
Simply type git lfs track when inside a repository.
Expected behavior
The command should finish nearly immediately.
