Performance Tests

Useful tool for writing performance tests: Japex.  Must remember to use that when we do our next round of profiling. Doug’s suggestion is that once we identify a bottleneck in the code, we write a performance test for it with Japex then try to optimize it until we reach the desired performance level. I’m not sure that our codebase is likely to see performance regressions in the same area again (I can’t ever recall having to reoptimize the same section of code), however having the test would be able to quantify how much of a performance benefit we get which would be a useful metric to know.
