Opera STILL using too much energy

  • My current Opera is:

    Version:	39.0.2248.0 - 
    Update stream:	developer
    System:	Mac OS X 10.11.5 64-bit
    

    Even with battery saver turned on, Opera still uses huge amount of energy.

    For instance a screenshot.

    This process which occupies entire CPU (100%) has following properties:
    Real memory size: 405MB
    Threads: 19
    Ports: 346

  • I forgot to add - when I force-killed that process, nothing seemed to change in the active tab. So that has to be some background process (updater?) or some kind of an extension.

    Any thoughts?

  • You can use Opera's task manager to see which process this is.

    Turn on the developer menu using 'View -> Show Developer Menu'
    Then go to task manager using 'Developer -> Task Manager'.
