228374 - Make (page) rendering multithreaded

Status: RESOLVED DUPLICATE of bug 40848

(SeaMonkey :: General, enhancement)

If you load multiple pages in multiple tabs or windows at the same time, this
isn't a lot of fun because apparently one single thread is used for rendering
everything. This is particularly annoying when you have a not so speedy dual CPU
rig where rendering of a *single* page is acceptably but not blazingly fast -
the pages block each other quite nicely, and the UI doesn't stay responsive (!),
with one CPU being fully loaded and the other one doing little more than
twiddling thumbs - this is not very smart. I assume making rendering
multithreaded would benefit just about anyone with a multi CPU rig, be it a PC
(including ones with Hyperthreading, but those are fast enough anyway), Mac
(dual G4s aren't that uncommon) or other machine.

Reproducible: Always

System config here: Asus P2L97-DS, 2x Celeron 300A, 448 MiB RAM, ATI Rage Fury
32 MiB AGP, Cheetah 36ES 18 GB on U2W HA. (Moz 1.5 load time with one empty
browser window is ~13-14 s, from the disk cache ~7 s.)

In case someone searches for these words: gecko multithreading
