1316865 - High CPU usage with empty profile, no tab and idle

Status: NEW

(Core :: Hardware Abstraction Layer (HAL), enhancement, P3)

Description

[Mathieu Leplatre [:leplatrem]]

- Firefox 49.0.2
- Ubuntu 16.10
- GNOME Shell 3.20.4

I created a new profile, and never used it. I leave the browser opened on the homepage and don't do anything.

Firefox takes between 20 and 55% of CPU (Dual core i7-6600U).

Hardware acceleration is on in about:support:

- Vendor ID	Intel Open Source Technology Center
- Device ID	Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2)
- Driver Version	3.0 Mesa 12.0.3

... I don't know where to look. I read https://support.mozilla.org/en-US/kb/firefox-uses-too-many-cpu-resources-how-fix)


Note: I've got the same problem with Firefox 52.0a1 (2016-11-10) (64-bit)

Same issue on my computer. FF take around 100 % of one core of the CPU (Intel Celeron 847). I run Ubuntu 16.10. Issue already there before installing the Flash Player add-in.

Comment 2

[Yuri Colombi]

Attachment: TOP command showing CPU usage

Comment 3

[Yuri Colombi]

Could be related to Xorg and compiz

Comment 4

[Yuri Colombi]

Seems fixed after a Ubuntu system update

Comment 5

[Mathieu Leplatre [:leplatrem]]

My system is up-to-date, and I even tried with kernel 4.8.7 which includes the latest Intel i915 drivers.

The problem still exists, but I'll close since some other applications are affected too.

Comment 6

[:Gijs (he/him)]

Can you take a profile with the gecko profiler when this happens? ( https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem )

Comment 7

[Mathieu Leplatre [:leplatrem]]

Thanks for your suggestion!

This is what I got:

https://cleopatra.io/#report=7ee0b84071ee50c7be70155e41ed01bc6f773831

I overlooked and couldn't see any alarming information, but I have absolutely no experience with that!

Comment 8

[:Gijs (he/him)]

It looks like it's just stuck in _poll . Which means I suspect bug 1057653, which has a comment pointing to bug 1274731. I'll ping that bug, I guess. Andrea, is there a way to diagnose whether the polling in this profile is really caused by the battery API (which is a bit surprising, actually, on a clean profile - I don't know anything that'd query it) ?

Comment 9

[Andrea Marchesini [:baku]]

We definitely should land bug 1274731.
