High CPU usage (almost 100%) on streaming radio site.



  • Very high CPU usage when listening to streaming radio (Sweden Broadcast Radio) on this site: http://sverigesradio.se

    Actually the CPU raises even before starting to listening to any audio, just when opening the site. And when starting listening to a radio channel the CPU raises even more.

    Vivaldi version: 1.12
    Computer OS: Ubuntu 17.04 64 bit

  • @nilzon FYI, for me:

    Once i closed that tab after finishing the test, my cpu returned to 7%.

    EDIT: My cpu is an 8-core i7, btw.

    Normal CPU usage.
    Similar to Conky screenshot above.
    Check your extensions, if you have any, or start Vivaldi from the scratch issuing the cmd's below. Open the terminal:

    vivaldi --user-data-dir="/tmp/TEST-VIV" &



  • No, tried that site (my favorite streaming radio site) again today, with the same problem. Even only opening the page on its first level: http://sverigesradio.se (no audio streaming) gives VERY high CPU load. Vivaldi usually have around 5%-7% CPU load when surfing on other sites, also with several tabs opened. So far my problem is only related to the site: http://sverigesradio.se
    opening that site, and the CPU-usage raises to about 100%.

    If anybody could give me a hint on the cause of of such problem, I would be most grateful. I usually listen very often to this radio site, so it is a big annoyance for me.

    NB: I have tried this site also in Firefox, without any problem. And Vivaldi works fine on any other sites that I have visited.

  • Update: Streaming audio on that site ( http://sverigesradio.se ), however seems to be the biggest issue. I has a major impact (100% CPU load) when listening to audio on one of the available channels. I have also now tried the corresponding site in Norway ( http://www.liveonlineradio.net/norway/radio-norge.htm ). The result is the same. Listening to a streaming radio channel gives the same high CPU. So I do not think this is an issue with only one specific site, it seems to be a problem with listening to streaming audio with Vivaldi in general.

    @nilzon Starting Vivaldi on terminal plus switch "--user-data-dir="/tmp/TEST-CPU" will not make any changes your 1.12
    In case the issue persists, it's something specific of your platform.

    If you didn't change anything, the result will be the same.

    Not only is that statement factually incorrect, it is patently illogical [did you not see my screenshot?]. Clearly there is a real problem with your current V deployment on your pc --i do not deny that-- but you simply cannot then extrapolate from your individual experience to make outlandish improperly-generalised claims like this. I presented you with DATA above, in my screenshots of the tests i did specifically for you, that absolutely proves your generalisation to be untrue.

    Have you done any of the recommended tests? If nothing else, assuming you actually do want to solve the root cause rather than just whinge about the symptom, you must conduct logical troubleshooting, in a methodical manner. The starting point, as always, should be to retest your problem site with a virginal V profile, then progressively build up from there.

    Ease up Steffie ... @nilzon's comment is a bit ambiguous and could just be saying he/she now thinks his/her problem is more general and not related to a particular site.



  • @cantankrus Obviously the general nature of this community is one in which opinions are shared, advice is sought, help is requested & offered, etc. For those requesting help, there is, or should be, an implicit obligation to not ignore it when it is extended. When an OP requesting help is faced with (a) suggestions for how to begin testing, (b) objective data proving incontrovertibly that the local problem is not a global problem, the appropriate response is not to continue the original line of complaints without either indicating whether any of the troubleshooting steps were undertaken, nor to ignore the supplied data that negates the generality of the complaint.



  • Hello Steffie.

    You have just lost a Vivaldi user, thanks to your comments in this forum.
    I have now switched to the "Slimjet Browser" (By Flashpeak). Slimjet does not having any issues when playing streamed radio. In addition they have a friendly atmosphere on their forum/support site.

    Good By (Forever)

  • Hmm, maybe an Issues page could be useful. I mean, a locked page at the Forum's home page where put some thing to do and control, before post anything. And also the basic stesp to reproduce in very common scenario, for expamle How to reset Vivaldi profile...*, etc.
    I mean, a dedicated thread (with disabled comments) where also advanced and skilled users can easily link, instead of browsing around and lost in thousand threads/post.

    Greetings



  • @steffie
    Agreed... just didn't see the necessity at that stage to get on the perfumed steam roller. :astonished: :grin:
