Description Alexey Proskuryakov 2015-02-04 09:40:04 PST
inspector/css/selector-dynamic-specificity.html is very slow on OS X Yosemite WebKit2, even in release build.

I'm going to add a Slow expectation, however it seems quite surprising that we have a big difference between Mavericks and Yosemite. Maybe that's a sign of a real bug somewhere.

Added the expectation in r179607.
Comment 3 Alexey Proskuryakov 2015-02-06 00:09:48 PST
Even with the expectation, the test frequently times out in debug builds. Here are some recent run times, in seconds:

150, 150, 150, 17, 82, 22, 150, 118, 24, 19, 18, 22, 134, 97, 150, 95, 27, 150, 150, 150, 53, 47, 150, 127, 102, 19, 95, 150, 19, 62, 133

150 seconds is slow test timeout.

Performance on Yosemite is still unreliable, but not anywhere that poor any more. This test usually takes around 2 seconds, but sometimes exceeds 20 seconds.
