Opera 21 CPU at 100%

    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.

    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).
