You can increase the logging level of the various classes in the git plugin
and the git client plugin in hopes that the logging time stamps and
messages will give some indication of areas that are slow.  Refer to
https://wiki.jenkins-ci.org/display/JENKINS/Logging for instructions to
increase log levels from the user interface.  The git client plugin source
code (https://github.com/jenkinsci/git-client-plugin) and the git plugin
source code (https://github.com/jenkinsci/git-plugin) will show you the
classes you can monitor and the logging levels.

You could try capturing periodic stack traces of the Jenkins process while
it is computing those changes.  The jvmtop (
http://stackoverflow.com/questions/6846049/profiling-a-running-java-application-in-command-line)
script seems like it could help there, without requiring recompilation or a
profiler.

You could  try running your Jenkins process with VisualVM as a profiler (
https://visualvm.java.net/profiler.html).
