Hello,

I have just updated the Git client to 1.0.4 and noticed that my build was hanging on the step:

Checking out Revision 9c65124b7c042f2427702e19ef9b24b2d7151191 (origin/branch)

After some investigation, it was running well, but the "checkout" was very slow. The thread call stack was often in I/O and zip related classes.
Previously the complete build of the project took 2 minutes, now with JGit the checkout was not completed after 20 minutes...

I have found a workaround (not tested yet) in JENKINS-17211:

-Dorg.jenkinsci.plugins.gitclient.Git.useCLI=true

Would it be a way to optimize this step in the plugin or provide a property in the Jenkins configuration interface to use the git command line tool ?
