 Mentoring a student in Google Summer of Code 2020 was a great experience. The student proposed to increase the performance of the Jenkins Git plugin by removing duplicate operations and by choosing the fastest Git implementation based on the size of the repository. The student added a performance testing framework and provided data from the framework comparing performance of the two different Git implementations. The data surprised us and led to performance improvements that are now available to all Git plugin users. Over 85,000 installations of the Git plugin are now running the code developed by that student as part of Google Summer of Code.
