There is ~15% preformance regression in OpenManifestEditorPerfTest#testEditorOpenMF() noticed only on windows.
We haven't made any changes to the editor that would account for this. Marking for M5 to do a bit more investigation,
We did not make any changes to the editor and do not have the resources to investigate further. Closing as WONTFIX.
Deepak, please take a look during M6.
Deepak, please reopen if you plan to look at this.
I will take a look during RC1.
The test seems to have an interesting history on Windows... It slowed down significantly in 3.6 - http://archive.eclipse.org/eclipse/downloads/drops/R-3.6-201006080911/performance/org.eclipse.pde.ui.php?fp_type=0 but then it improved significantly in 3.7 (probably back to 3.5 level) - http://fullmoon.ottawa.ibm.com/downloads/drops/R-3.7-201106131736/performance/org.eclipse.pde.ui.php?fp_type=0 Unfortunately for 3.8 the test results for windows seem to be missing on the downloads page - http://fullmoon.ottawa.ibm.com/downloads/drops/S-3.8M4-201112091447/performance/org.eclipse.pde.ui.php?fp_type=0 http://fullmoon.ottawa.ibm.com/downloads/drops/I20120320-0800/performance/org.eclipse.pde.ui.php?fp_type=0

I do see a small slowdown in 3.8 With Master Elapsed Process: 255ms (95% in [249ms, 261ms]) 3.7.1 Elapsed Process: 227ms (95% in [221ms, 233ms])
I ran the test with all miletsone builds, and there seems to be a gradual slowdown, once around M3 and then around M6/M7 3.7 Elapsed Process: 156ms (95% in [154ms, 158ms]) Measurable effect: 3ms (0.2 SDs) M3 Elapsed Process: 167ms (95% in [165ms, 169ms]) Measurable effect: 4ms (0.2 SDs) M6 Elapsed Process: 170ms (95% in [168ms, 172ms]) Measurable effect: 3ms (0.2 SDs) M7 Elapsed Process: 179ms (95% in [177ms, 181ms]) Measurable effect: 3ms (0.2 SDs) (Note: I increased the number of test runs from 25 to 500 to increase the accuracy)
Not sure if we will get to this in 3.8/4.2, the slowdown is not much. Deepak, if you think you will have time to get to it for RC2 feel free to to set milestone as needed.
Slowdown is not much. We can close this as WONTFIX. Dani?
