Static git operations on the Gnome GTK tool-kit repository. There is one test that runs in less than a minute. The test looks to be single-threaded.
Topdown profile shows a higher amount of branch mis-prediction.
AMD metrics show little floating point and not much L2 activity. The opcache miss rate is low.
