(Keywords: meta)

This is the metabug for Fission pageload issues.

Methods for measurement: raptor (once support lands, or by forcing fission on); local browsertime runs, etc. Emphasis on visual metrics (and things like FirstPaint).

tp6 browsertime results run locally with the fission setTimeout patch included - opt build, high end linux desktop (28core), small amount of other activity on the machine (rarely):

Some videos from that run:

Commandline (fission):
./mach browsertime --browser firefox --visualMetrics=true --firefox.binaryPath obj-opt/dist/bin/firefox --firefox.preference fission.autostart:true --iterations 5 --video=true <URL>

Priority: -- → P1
