Description Frederic Fusier CLA 2008-03-07 07:30:50 EST
Verifying build I20080305-1100, it looks like there's a serious regression
on test PackageExplorerColdPerfTest#testOpen(): between -69.0% and -103.2%

Note that the +3.1% result should not be considered as it looks more than a bad result on the baseline. Next baseline (3.3_200706251500_200802221710) is back to normal and so, also shows a big regression on this box.

Set as minor because the test time is less than 100ms so, it should not be noticeable by user. However, I think it could be interesting to increase the test time to have more precise numbers (100ms is the minimum, I would say that 200ms for the fastest box would be great!)

The numbers are too low (<50ms). As we still want to keep this test in order to detect big regressions I changed the assert condition for that test: it now uses absolute and no longer relative numbers.
