Description

6 years ago
The tail end of our regressions got significantly worse in 18, see bug 798130. It would be good to get a list of build ids that exhibit signficantly worse startup perf. I'm mostly interested in the right side of the histogram, ie values over 9s, 15s and 30s.

analysis of SIMPLE_MEASURES_FIRST_PAINT in 17 nightly vs 18 nightly

Analysis of SIMPLE_MEASURES_FIRSTPAINT from Telemetry did not show evidence of performance regression in FF18 nightly builds, including on or around 2012.09.11. This does not rule out a regression, but there is not conclusive evidence in this data, and the data examined was not adequate to isolate a regression in any particular build.
