Opera 21 CPU at 100%

Have you tried restarting your computer since the update ?.

Yes and it still consumes 100% of the CPU. Having to restart a computer for a browser upgrade is only something Microsoft would require as well. I did see many issues with "Chrome Help" doing the same but in much earlier versions. So it appears as if Opera has re-introduced an old bug.

I went back to Opera 20, no reboot and no high CPU utilization. I'm going to see if Opera Next has this issue; if it doesn't then Opera 21 is just a flop and should be avoided.

Opera Next (Opera 22) does not have this issue. So whatever the reason that Opera Helper wants to consume as much CPU resources that it can is isolated to Opera 21. I just tried the latest Opera 21 build as well, it suffers the same as the previous build. So until Opera Next graduates to normal Opera, I'll stick with Opera 20.

Same for me even on opera next 22. Happens only occasionally after a certain period of time. Quitting Opera and relaunching helps, but eventually 100% Opera Helper CPU usage returns. Does not happen with Chromium Helper. Any Ideas?

i dont get 100% cpu but it eats up all my memory they have gone chrome route with opening an instance in a separate process in task manager for several tabs by the looks of it which i hate to a point i think to stablize it but i would think that telling people to keep tabs down to so many would be a better option.

On Opera 21, my 8 CPU macbook is running hot, with 6 CPUs pegged by Opera Helper. I'm not really doing anything exotic, other than having many tabs open (around 100).

Here's "top -o cpu":

Here's a flame graph of my Opera Helper CPU time, including both kernel and user-level stacks (kernel is above the grey separators):

http://www.brendangregg.com/FlameGraphs/cpu-opera-helper.svg

The 6 towers you see are for each of the 6 Opera Helper processes.

For background on flame graphs:

http://www.brendangregg.com/FlameGraphs/cpuflamegraphs.html

This particular flame graph was generated using:

$ sudo bash
# dtrace -x ustackframes=200 -n 'profile-199 /arg0 && execname == "Opera Helper"/ { @k[stack(), ustack()] = count(); } profile-199 /!arg0 && execname == "Opera Helper"/ { @u[ustack()] = count(); } tick-30s { exit(0); } END { printa("%k%@d\n", @u); printa("%k-%k%@d\n", @k);  }' -o out.operahelper
# cat out.operahelper | ../FlameGraph/stackcollapse.pl | ../FlameGraph/flamegraph.pl --title "Opera Helper Flame Graph" > out.operahelper.svg

With the flame graph software from: https://github.com/brendangregg/FlameGraph

Hope that helps.

I forgot to add my specs - OSX 10.6.8, 4GB ram.

Opera 20 stable and Opera 21 Next are getting even worse with regards to CPU resource usage and memory as well. After 2 hours browsing, I have easily 50-70 processes running called "OPERA HELPER".

Each of these (could be as many as 50-70) are gobbling up 20-100 mb of memory. I have 4GB memory on laptop but I easily run out of memory because of Opera.

The CPU is constantly on 80% or above, at times hitting 100% on both cores of the dual core processor.

The thing which really sucked about Opera pre-Chrome version was CPU and resource usage. Now it seems the problems returned in another form. I don't know what is Opera doing about this issue. It makes things insane to the point I want to stop using the browser, if it wasn't for over 15 years I am with Opera.

I believe the focus should be on making the browser resource efficient and not the try to catch up with whatever Chrome/Chromium comes with.

Efficiency was always Opera's strength till about Opera 11 or 12 release when the team started to fool around with Unite and then things started to go downwards.

Why would I use a Clone of Chromium if I can have Chromium.

EFFICIENCY and SWIFTNESS are the keys for me if I continue using Opera or not.

Thanks.

Was that actually necessary ?. I mean the rest of your post was a valid concern about a problem you seem to be having, but then throw in a quick dig right at the end.

Anyway, have you tried 'Tab hibernation' in 'opera://flags' ?. I think it's still experimental (though i could be wrong), but may help with your problem.

Hi guys,

Please go to View menu and enable Developer Tools. From the new Developer menu, open the Task Manager.

What process is using so much CPU? Please quit it using the Task Manager and let us know if resource usage goes down.

hola,
tenia el mismo problema, y lo solucione cambiando el tema de opera, la tarea opera helper que agotaba mi cpu era la de acceso rapido porque el tema consumia los recursos, cambie a un tema sencillo y todo se soluciono. ademas no tengo extensiones web.

I'm running opera 41.0 on a mac, and are now having this exact same problem. I tried to switch to opera beta (42.0), and the problem is still there!!!!! In 2016!!!!!

//Windows 7 64x opera 42 42.0.2393.85

i had the same problem and i solve it my going to task manager-process-show processes from all users-and if you see a svchost is taking up a lot of cpu right click and go to services,then try and find the service and stop it.

for me the service "Windows Update" is starting automatically and its destroying my 2 core cpu.
if you have a similar problem go to the task manager-services tap-services...(bottom right)-then you find the Windows Update service-click it and in the menu and in the startup type switch from automatic to manual and you're done
if the service starts you can go to the services and stop it

!!WARNING!! don't stop ANY services without doing you're research...i did it once and i ended up struggling to fix it with a command prompt from the windows troubleshooting future.

Again this problem.
Opera 42.0, Macbook Air 11 early 2014.
The laptop gets hot while using Opera, the activity monitor shows huge numbers of CPU usage (up to 90-130 % CPU) either for Opera or Opera Helper processes (or both), especially while using Adobe and its products (adobe connect, flash, etc.). Sometimes just for no (visible) reason.

The problem started about 2 months ago, I have no clue what version of Opera it was, but it still remains and consumes my battery in huge amounts, plus melts my table and everything where my superhot laptop is (the insides are clean, seems not to be the dust problem).
