[gentoo-user] Hungry firefox

[Peter Humphrey]

Hello list,

Has anyone else here noticed firefox consuming 15% or so of CPU time, even 
while it's not supposed to be doing anything? This is version 31.5.3, with 
just AdBlock Plus and YesScript added. I have remerged it and saw no 
difference.

[ebuild   R    ] www-client/firefox-31.5.3::gentoo  USE="dbus jit minimal

I was going to post no, but then I realized I have ~36.0.1 installed. I
also have more plugins installed. Now that I think of it, I updated to
unstable because of some issue I had, but for the life of me I can't
remember what it is.

I am using Adblock Plus, DownThemAll, Ghostery, NoRedirect, NoScript,
RequestPolicy, WOT, and Xmarks - no issues on 36.0.1. I stared at top
for about a minute and didn't notice any CPU usage.

Occasionally, I've had javascripts running away with the CPU,
which stops when I kill FF & restart it.  That's just bad JS programming.

Thank you gents,

Mention of scripts lit a lamp, so I closed the Twitter tab. CPU use went 
straight down to nothing.

Maybe I should have a word with the Twitter devs. At any rate, I can at 
least poke around a bit less blindly.

Thanks again, and sorry about the noise.

Your query is not noise : abuse of JS needs to be followed up promptly.

Do you have to kill the whole browser and not just the offending tab?
That's just bad programming...

Just the offending tab _should_ do it.

> That's just bad programming...

Probably.  From what I've seen, the web is build almost entirely out
on "bad programming".  I'm not sure it's even possible to do good
programming in PHP, though you can in JavaScript.

Do you use FF yourself ? -- if there's only  1  tab open & you kill it,
it kills the whole FF job too.  That's usually the circumstance :
I've finished reading 'Guardian' (eg) & am doing something else,
but the fan is working busily, wearing itself out & irritating me ;
when I kill FF -- however I do it -- everything calms down.
No, I'm not wasting my time complaining to the Guardian IT dept ...

No, that's why I had to ask :)

But you can kill a misbehaving tab and everything else is fine? That
wasn't what the previous post implied.

To change that, enter "about:config" in the address bar, dismiss the
warning if you haven't already, then search for
browser.tabs.closeWindowWithLastTab and toggle that pref to false.

I hate it when browsers do that. Fortunately, we’re not left standing in the
rain: about:config → browser.tabs.closeWindowWithLastTab=false

Dammit, I should fetch mails more often before replying. ’tis the second
time in as many days that I repeat someone’s answer unknowingly.

Don't worry, I read yours first (grin).
Thanks to you + <<Q>> : indeed, it works at once.

Stroller mb reassured that the Guardian hasn't left JS hanging for some time.
Perhaps they did get enough complaints or simply a new JS guy/gal.

The Guardian has always been bad for javascript.

3 or 4 years ago just following a link there could beachball Safari on my Mac.

I think that was when I started using the beta versions of Webkit - I've stopped now, but there was a year or two where the Guardian rendered the standard version of Safari unusable.

 Installed versions:  31.5.3(01:48:14 AM 03/28/2015)(bindist dbus gstreamer
jit minimal



Well yes and no. Not according to htop. Seamonkey is the resource hog;
or using the most resources (40-60 %). Firefox is 1-4%. I keep both
open with dozens of tabs. The sad thing is my (8)( core amd 8350
with 32 Gig of ram is barely using (1) core, unless I compile a 
big multi-thread package. What I do have is almost a full second of 
keyboard response latency. I can close both and the system is snappy
on response. I open either one (FF or SM) and the 3 dozen or so tabs
and it's back to keyboard lag; even though the resource utilization is
scant (1-1.5 cores/8 and 5300/32093MB).


Since the kernel dev folks have change so much over the last few years.
I figure I need to take a long hard look at what is enabled in the kernel,
and how resources are awakened or idle'd via some kernel-profiling. It's
most likely some advanced power conservation feature(s) that need tweaking,
is my best guess.

I have a system with plenty of extra, expensive ram and idle cores should;
it not be sluggish, uniless a big hog of a single threaded process
is not being properly managed.

Even when my browsers are not (actively) being use but open, I get
the horrible sluggishness now; and I'm running lxde.......not kde.

Sometimes I can hardly type it's so bad.  I have always had lots of 
tabs open for years and not experienced this sort of lag. Minimal resource
utilization, but horrible lag.

I've installed and ran' sys-power/powertop and it has some interesting
information; but theres still no conclusion as to what is causing
this inherent systematic latency. I do suspect FF and SM and Thunderbird
are part of the problem, but overal resource utilzation is well below 20%
(ram and cores) all the time, except when compiling.


hth,

James
