Vivaldi uses so much resources!
-
Even when it's just running mail with no other tabs open. It seems to be worse when you use the browser with a few tabs then close them. It seems to act like they are still open. Look at Process Explorer to see all the instances of Vivaldi running sometimes. Like 20+. It's often using more resources than anything else on my system and there's nothing going on with it, just displaying one tab with nothing updating.

@viv2u Each open tab and extensions uses ressources.
You can hibernate background tabs and workspaces by context menu to save ressources. -

Hi, Vivaldi use 1-3% in the task manager with 20 tabs, some web panels, 4 mail and two calendars.
Some user report high CPU usage with mail, disable it for a test.

@mib2berlin Well...
About 50 tabs in windows, of which all but 2 are hibernated. I don't use any of the Vivaldi services (panels, mail, calender, tasks, back-rubs, or whatever garbage is in there).
Vivaldi does use rather a crapton of resources. -
@182jd 37 tasks with two active tabs looks like many extensions.

OK, you don't use mail but is it enabled?
The number of tabs doesn't really change the CPU load, I setup session with up to 2300 tabs to test bug reports, no high CPU usage.
It must be something else.
I had the same issue with adding one feed to Vivaldi but never could reproduce it again, for example.
By the way, 80% of all issues in Vivaldi are caused by Chrome extensions.
Test Vivaldi in a clean profile, install and change nothing and you will know.Cheers, mib

No to mail.
I agree that it must be something other than the number of tabs: The browser
According to Vivaldi's process manager, my extensions have around zero impact on CPU usage. Since I've found Vivaldi to be quite resource-munchy from the day I installed it, and there's nothing else indicating it might be the cause; Occam's razor says Vivaldi.
It's not that I particularly mind - my CPU will keep up.
It was mostly that the OP posted a - in my opinion - rather obvious Fact of Life. Then finding replies denying it, pointing to hibernating tabs, caused my cola to leave my body through my nose.Just wanted to back up OP; never expected a solution for it

Hm, if it only happen on your system it is not Vivaldi, I have 6 different Vivaldi install and no high CPU usage on any.
Create a new profile, install and change nothing and test this, then you know.
It could be anything, worst case is a broken profile, Chrome extensions cause only 80% of all issues in Vivaldi.
-
@mib2berlin I've had multiple profiles, on multiple systems throughout the years and never had low CPU usage on any.
It's not like I ever expected it to be low, though; Vivaldi is a browser packed with more features than anyone will ever use - not just a bare webview wrapped in a minimal GUI. With that in mind, I think the CPU usage is mostly what one should expect. Just not low

Hm, I have 6 Vivaldi installs, 3 on Linux and 3 on Windows 11, some with two profiles and all have 0-3 % CPU usage, with 10 tabs or in one test session with 2300 tabs.
I test 6.5 with 800 tabs for 24/6, no slowdown, no lag.
After many tests I gave up to try to reproduce this.
No extensions, no third party security software.A user report in another thread high CPU usage, it is a github page cause this.
If I cant reproduce this in Chrome 122 the user can report this, the developer can look into.
We had some reports about constant high CPU usage but no tester and/or developer could reproduce this ever, how should they fix this?
I fear this will happen for some user but the Vivaldi team cant do anything about.It look the same on Windows:
