I just had a precheckin fail in BaseLineAndCompareQueryPerfJUnitTest. I'm not sure a junit test is really a good place for perf testing like this. Between JVM optimizing at runtime and possibility for machine CPU pollution, I'm surprised we haven't seen this fail before. Just wanted to mention this in case others see it or someone wants to take a closer look at the test...
