Re: [eclipse-dev] Fw: [Bug 215464] Regression in org.eclipse.core perf test: StartupTest. testApplicationStartup (aka 'Core Headless Startup')

I also think it is a little odd. Something can change in the system that artificially improves performance also. In this case, imagine if we dramatically reduced the number of source bundles from one release to the next. All of a sudden our start up performance numbers would have improved but nothing would have been done to actually make the system faster. A product with the same amount of bundles from one release to the next would see no improvement in performance.

Am I the only person who thinks this is odd?

To me, the grey coloring means "there is something wrong with the test (or
the system has changed in a way that invalidates it), so the result isn't
interesting" -- I don't actually care whether it's slower or faster. For
example, ongoing fixes elsewhere could cause the test to run faster, making
the test *look* like it's working again, even though it's still not

Note that when a degradation comment is set on a test, the fingerprint bar
becomes gray only if the test result is negative.

I released a degradation comment for the core headless startup test
(StartupTest.java) which points to this bug to explain the degradation.
