+Benchmarking
+============
+
+Benchmarking is useful to test that an existing patch does not degrade performance.
+
+`The Grand Unified Python Benchmark Suite <http://hg.python.org/benchmarks/>`_ has a collection of benchmarks for all
+Python implementations. The documentation for the benchmarks can be found `here <http://hg.python.org/benchmarks/file/9a1136898539/README.txt>`_.
+
+Note that the suite is intended for testing against performance regressions rather than optimizing code.
