[Blocking Requested - why for this release]: Bug 1033549 introduces a lot of data process for per-app data usage which delay chart rendering about 1000ms. Notice solution for bug 1064491 could solve this issue as well.
triage: significant perf regression.
blocking-b2g: 2.1? → 2.1+
Attaching some videos to prove how the patch for bug 1064491 solves the problem.
Notice how the chart is completely rendered almost immediately after launching the application.
Now notice how the render of chart lines, dots and Y-axis labels are delayed until the application breakdown is completed.
Attachment #8502115 - Attachment description: Usage application in 2.1 → Usage application before bug 1064491 patch in 2.1
