564125 - [HTML5] Ts Shutdown, Cold MAX Dirty Profile increase 5.80% on Mac OS X 10.5.8 Firefox

Status: RESOLVED WONTFIX

(Core :: DOM: HTML Parser, defect, P4)

Description

[Henri Sivonen (:hsivonen)]

Landing the HTML5 parser caused a 5.8% Ts shutdown regression on Mac OS X 10.5.8.

This bug is for investigating and tracking the problem. Currently, it seems that bug 563899 is to blame.

What are the absolute values of ts shutdown before and after? Bug 563899 only operates in 100ms increments.

Ugh, sorry, I misread bug numbers. I have no idea about bug 563899; I thought we were talking about bug 519893. Ignore my comment from above.
