1160810 - nightly on x86 consumes a large amount of cpu

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[Jamie Charlton (:Jamie_)]

while running on linux x86 the nightly will consume large amounts of wpu with little to no reason. while starting nightly cpu consumption on a i5 quad core jumps from 4 to 40 percent and when on a open window with just a blank tab (this is a decent amount of an i5 quad), it doesn't idle it it varies from 4 all the way up to 20 with no activity.

Without more info or a reproducible test case, it will be hard to chase this down. https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler is another possible tool for finding Firefox CPU usage causes.

Im not sure how much this helps gavin, but this was the profile idling with just Cleopatra open then clicking the restart firefox button on the profiler.

I'm sorry, but I don't have the time to dive into this right now. You could try posting to dev.platform or seeing if someone in #developers can help you debug it.
