git status command is very slow

Question

My git status command is getting slow recently.

I tried to trace the execution:

GIT_TRACE=1 GIT_CURL_VERBOSE=2 git status

Output:

10:24:37.249722 git.c:344               trace: built-in: git diff-files --ignore-submodules=dirty --raw --

And I found in the two steps it take 10 seconds:

10:24:26.962895 run-command.c:640       trace: run_command: git-submodule summary --files --for-status --summary-limit 1
10:24:37.013868 git.c:576               trace: exec: git-sh-i18n--envsubst --variables 'usage: $dashless $USAGE'

My git environment:

• macOS 10.13.4 (17E199)
• git version 2.17.0

Is there anyone coming into the same issue? I'm not familiar with the details with Git.

Try first to check if the presence of submodules migh influence the git status performance, using the --ignore-submodules[=<when>] option:

git status --ignore-submodules=all

Also, make sure your repo is clone locally, not on a remote drive, which would add latency to any Git operation.
