git debug options

[!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?

OPTION	DESCRIPTION
GIT_TRACE	Enable general trace messages
GIT_CURL_VERBOSE	DEPRECATED: Print HTTP headers (similar to curl -v)
GIT_TRACE_CURL	Print HTTP headers (similar to curl -v)
GIT_TRACE_CURL_NO_DATA	-
GIT_SSH_COMMAND="ssh -vvv"	Print SSH debug messages (similar to ssh -vvv)
GIT_TRACE_PACK_ACCESS	Enable trace messages for all accesses to any packs
GIT_TRACE_PACKET	Enable trace messages for all packets coming in or out of a given program
GIT_TRACE_PACKFILE	Enable tracing of packfiles sent or received by a given program
GIT_TRACE_PERFORMANCE	Enable performance related trace messages
GIT_TRACE_SETUP	Enable trace messages printing the .git, working tree and current working directory after Git has completed its setup phase
GIT_TRACE_SHALLOW	Enable trace messages that can help debugging fetching/cloning of shallow repositories

    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.
