Description Frederic Fusier CLA 2010-09-08 10:38:13 EDT 
Verifying N20100904-2000 results, it appears that there was a regression since the beginning of 3.7 dvpt on perf test:
 - BenchFileStore#testStoreIsReadOnly()

It took me a little while to identify it because the difference with the baseline is often less than 100ms. As no user can detect such a difference, I had a filter to exclude this kind of failures from my report.

As it may be interesting to understand why such a regression can occur, I have removed this filter, hence reporting it only now... Sorry for being late :-S

Note that this regression only occurs on windows machines, not on Linux ones...

The regression is a result of newly added functionality to Windows natives. At the beginning of 3.7 we added symlinks support (Bug 318170), also ported back to 3.6.1. I'm going to mark the test grey.
