Having a realistic performance test for various areas will allow us to find offending commits. Ideally, it would be possible to run the same tests on other operating systems so we can identify points for improvement. It would be good to test for specific cases as well, such as: * Network operation with a packet filter in use * Typical disk workload * Performance of a multi-threaded program > Insert good performance testsuite examples here It would be nice to easily test commits between particular dates.
