<![CDATA[Opera.exe instance swallows more than 50 to 60% of my CPU]]>Opera has the habit of starting another Opera.exe and swallows more than 50 to 60% of my CPU.
Viewing a TV doc suddenly Opera starts another .exe and System Explorer shows CPU in the red aria.
Stopping that proces dropped the CPU to normal.
I don't understand what's happening.
There are multiple Opera.exe active in the list of processes.
But this bug that drives up CPU usage to almost 100% is annoying.

So I deleted it, to see if this may be the culprit?
Thanks for suggestions.

I have Avira browser safety installed.

To find out what process is using the CPU you need to use Opera's task manager, not the Windows task manager.

By the way, my system has 8GB memory and it more than fast enough for any browser or video.

It usually happens when Opera is left for a while idle.
But since there is no distinction between several Opera.exe operations running at the same time, I can't find out what the difference or purpose is, even with System Explorer. It all leads to the same process?
So if it jumps up again, I kill the most CPU consuming one, and another Opera session is still working OK.

I have found the task-manager, see what that will display?

Thanks so far for the help.

You will find it in the Developer menu if you have it enabled. In there you can find the exact process in Opera that is causing the high CPU usage.

Memory is cheap these days. Buy some.

He said CPU usage, not RAM.

brnrds

Still waiting for an answer, just again 60% CPU time.
Stopped that process and Opera still working, so a totally unnecessary Opera process absorbs my CPU now and then.
There is no indication whatsoever of a virus or malware.

It may well be a plugin that's installed in Opera, not Opera itself. As joshl suggested, try running without any addons.

At what resolution are you trying to watch it anything over 720p will tax your system considerably if you choose a video on youtube and change it's resolution you should see comparable drops in CPU usage as the resolution drops off... Also if you're not using a discreet video card then it would help alot as most new GPU's are capable of decoding video via it's hardware thereby not using so much CPU resources

You might achieve that by disallowing everything for the private/incognito mode then go there. Not every extension might go off that way, so if you don't care, you might just disable them all completely to see what'll happen. Well, some hardware acceleration or failing driver might be, huh? 😕

See, if it is an opera.exe process, it might be something that you (or something else there) have kinda installed there but which doesn't seem to behave - like either incompatible or having been laid with an error. So if it's like that, the thing might start and get ^running^ but burning rubber while doing that.

I noticed that Opera often when idle jumps into that CPU consuming mode of over 60%.
Killing that Opera.exe won't shut down the browser, so what is it, that's it's doing ?
I can't figure out what the difference is between Opera.exe and Opera.exe where one is the normal operation and the other a useless running one?

Plus it's normal load which may in total run up to 80%.
I turned off the crashreporter, which was also causing high CPU while there was nothing to report, no crash.

It happens in idle mode, but also on the run.
It's not specified in Process explorer or taskmanager, only Opera.exe ?
I kill that high CPU process and Opera is still available, not shutting down.
So I wondered maybe an update check? Or whatever?
Can't get a hold on that mysterious Opera behaviour.
If browsing is significant slower, it's mainly caused by an open Opera, even if you are using another browser at that time.

See process ID (pid) in Windows' task manager and then, in Opera, go to Menu > Dveloper > Task Manager and find out which process is that.

This started again by swallowing 57 % of the CPU. Driving the CPU to it's limits.
I can terminate it and the browser continues as normal, so there is no crash at all to report.
By the way the crashreporter never seems to end its "report".
I have a Windows 7 Ultimate 64 bits CPU which is more than fast enough for modern use.
I'm considering to delete that "reporter".

This allows each tab/extension/etc to have its own access to your CPU's cores and RAM. This also means that if one of them has a problem and needs to terminate it is much less likely to crash the whole browser.

If you are having a problem with Opera using all of your CPU you either have a weak system or you have something wrong. Please post your full system specs (OS version and bit rate, CPU (make/model) and RAM). The version of Opera you are using would also be good. And don't say something useless like 'the latest' Post the full version number.

Next, open up Opera's Task manager (Opera menu > Developer > Task manager. you might have to enable the developer menu) when you are having a slowness problem and tell us exactly which process is using all of your CPU.
