High CPU usage when doing barely anything
-
Sometimes removing and re-adding of extensions had helped me in the past, happend very rare, with high CPU usage.
-
@DoctorG I thought about it, but it can't be the extensions, as it does it with --disable-extensions and in Private mode (which has no extension)

I'm trying on another computer with a fresh install, it has sync and the problem is not there.
However it hasn't sync my full history, it only starts from 13th of August 2024.
Is there any way to get it back ?My history set to keep forever so I don't understand why.
-
@megosu
You can copy the history file from your other system over.
If you get problems the history file is may corrupt.I never understand why the Vivaldi team allow "Forever", many user get issues with this hundreds of MB big file.
-
@mib2berlin what is the rule for history sync ? isn't it supposed to sync all of it ?
-
@megosu
I don't know how it exactly work but Vivaldi doesn't sync the whole history. -
@mib2berlin it works fine on the test computer, even with my 50MB history file.
what other file should I try to focus on to fix this issue ?

I also took screenshot of Vivaldi task manager before enabling Feeds and after.
idle wake ups are going through the roof instanty:Before enabling Feeds:
After enabling Feeds:

To be honest, I would not trust this profile anymore.
You could try the file Preferences which contains a lot of stuff, settings, workspace names, mail accounts and much more.
Why don't you use your test profile on the same system, copy a profile from one system to another is not really recommended. -
@megosu
Is this on your old profile?Opensuse Tumbleweed x86_64 KDE 6.2 X11, Windows 11 Pro, Vivaldi latest
HP Probook Intel(R) i5-8350U 16 GB, GPU UHD 620, SSD 256 GB
Miniforum-B550 AMD Ryzen 7 4700G 16 GB, Radeon Graphics

@mib2berlin yes, it is my "old/current" profile
-
I found something !
What I tried:
on a test computer, I copied my Default folder, I had the same issue.
When I cleared the content of "AppData\Local\Vivaldi\User Data\Default\Storage\ext\mpognobbkildjkofajifpdfhcoklimli\def" then it worked
- In this blank folder, when I copy only my IndexedDB folder, then I have the issue.
- In this blank folder, when I copy all folders except "IndexedDB" folder, then I still have the issue
- In this blank folder, when I copy everything else but IndexedDB and
"Service Worker" then it works ! - In this blank folder, when I copy only my "Service Worker" folder, then I don't have the issue. Interesting because this folder ruins everything when put with the others. So it must interact with other folders.
And finally, on my real computer, I renamed both these folders, and it worked perfectly !
Would you know what could I lose by deleting these 2 folders ?
I'm not sure what happened to these files, it would be interesting to see if this fix works for others having this issue. If it does, it could be worth it to share it with Vivaldi team for a proper fix.
@brianrubin, @pointed-stick, @invenio ,@Vojtik69 :
can you confirm if the following helps you too ?- Close Vivaldi
- in C:\Users\username\AppData\Local\Vivaldi\User Data\Default\Storage\ext\mpognobbkildjkofajifpdfhcoklimli\def
rename these 2 folders (add ".old" at the end for instance):- IndexedDB
- Service Worker

@megosu
Hi, I don't have this issue using feed and mail.
mpognobbkildjkofajifpdfhcoklimli is the mail data base, maybe this was corrupted.
If you enable mail and feeds again Vivaldi create a new one, this can help with many mail issues.
I never thought this is the reason for high CPU usage.
Nice find! -
@mib2berlin it's really weird, as I never used email or calendar on Vivaldi, and I only started using feeds some months ago.
Good to know I'm not losing anything by deleting these 2 folders.
-
Hi, Windows 10 user here.
I enabled the Mail/Calendar/Feeds feature on my computer and a friend's computer for the first time and CPU usage spiked and the returned to normal levels after disabling it and restarting the browser.
Hopefully someone from the dev team can investigate.
-
@ProductUser
Hi, this could be hard because the developer never could reproduce it.
I could reproduce it once with adding one feed, remove the feed and add it again solved it.
So we need a bit more information what you are doing, enable the feature alone was never reported here causing the issue. -

I'm experiencing similar problem with any activity being responded with a long time of a single core overload. No Mail, Feed or Calendar, as I did never use any of these, Task Manager shows Browser going at 100% or more, Network Utility Service at 40%. Will take another look and review other ideas from this thread, but opening just few tabs kills performance - I have to restart and then close tabs after viewing them, this is the only way to maintain somewhat responsive browser. Considering that mere weeks ago I was able to open ~50 tabs to consume them in LIFO order without any glitch, this is a considerable deterioration.

@szczurnik
Hi, try the internal task manager, one tab or a extension can cause such a high CPU usage.
Open with Shift+Esc.Cheers, mib
