[!TIP]
commit 14e2411, commit 81590bf, commit 4527aa1, commit 4eee6c6 (07 Sep 2016)
Use the new GIT_TRACE_CURL environment variable instead of the deprecated GIT_CURL_VERBOSE.
GIT_TRACE_CURL=1 or GIT_CURL_VERBOSE=1
GIT_TRACE2_PERF_BRIEF=1 and GIT_TRACE2_PERF=~/log.perf
GIT_TRACE or GIT_TR2
How can I debug git/git-shell related problems?

AMD Radeon graphics driver

- * AMD was contacted but no response...
  diagram from Windows 10 2018
  microsoft/terminal issue 9744
- Git Bash (mintty) is extremely slow on Windows 10 OS
- #1071 : 2.11.1 slow enough to make it unusable in Windows 10 x64 - upgraded from 2.9 lighting fast
- #1070 : Git commands have a 2-3 second delay before returning to the promp
- #1129 : git commands running slow as hell
  I had the similar issue as yours on my Lenovo e450c laptop. And found the performance turned back to normal when I disabled AMD Radeon graphics driver in Windows device manager and switched to integrated Intel HD graphics.
