  Foundational software libraries such as ROOT are under intense pressure to
avoid software regression, including performance regressions. Continuous
performance benchmarking, as a part of continuous integration and other code
quality testing, is an industry best-practice to understand how the performance
of a software product evolves over time. We present a framework, built from
industry best practices and tools, to help to understand ROOT code performance
and monitor the efficiency of the code for a several processor architectures.
It additionally allows historical performance measurements for ROOT I/O,
vectorization and parallelization sub-systems.
