If you have ever received an automated mail about a performance regression, and then 10 more, you probably are frustrated by the volume of alerts. 6 months ago, I started looking at the alerts and filing bugs, and 10 weeks ago a little tool was written to help out.
What have I seen in 10 weeks:
1926 alerts on mozilla.dev.tree-management for Talos resulting in 58 bugs filed (or 1 bug/33 alerts):
*keep in mind that many alerts are improvements, as well as duplicated between trees and pgo/nonpgo
Now for some numbers as we uplift. How are we doing from one release to another? Are we regressing, Improving? These are all questions I would like to answer in the coming weeks.
Firefox 30 uplift, m-c -> Aurora:
Firefox 31 uplift, m-c -> Aurora (tracking bug 990085):
- 23 – regressions (5 CART, 3 TART, 2 SVG, 2 TP5, 2 TResize, and a few others)
- CART regressions are mostly fixed already!
- 10 – improvements (Kraken/V8, Linux64 SVG, OSX 10.8 TART)
Is this useful information?
Are there questions you would rather I answer with this data?
