CPU usage seems quite high
-
Dear Vivaldi Team,
I don't want to complain because I'm very satisfied with Vivaldi. Although I haven't fully transitioned to your browser yet, I've already fully adopted your email client. I would like to note that whenever I open the browser to check my email, the cooling fan always turns on. The memory usage is low, but in my opinion, the CPU usage seems quite high. Currently, it's the highest among the applications I use. Could you please comment on this?
Best regards,

@A60 add some informations on your pc (os version,cpu, gpu, how much ram and so on).
Try to disable efficiency mode and see if it helps (you see is enabled by the green leaf in task manager)

Just vivaldi run CPU, even Photoshop of Chrome with 20 tabs don't do that. I understand you may to help me I better to answer question but even without any tabs vivaldi heat my PC.

Hi, some user report high CPU usage with enabled mail/feed/calendar client.
Try to disable it for a test.Cheers, mib

I am going to use vivaldi just as mail client. Move from another client. Hope Vivldi will solve issue with mail client.

@mib2berlin Kindly may you point me that certain topic to follow please.

Hi, I use Vivaldi as mail client with 5 accounts and 2 calendars but I get 1-2 % CPU usage on Windows and Linux.
To disable the client is only for testing if it is really the reason, you can enable it again after testing.
No need to delete anything.
Search the forum for high cpu and you will find many posts about.
How many accounts you use, which provider, IMAP or POP3?Cheers, mib

On Windows 11 I have only 4 accounts at moment:

@A60 I don't think I made a separate topic for it - but I have commented several times about my 60% CPU usage with mail. Someone else mentioned they get it too.
I have one question: are you using IMAP or POP3 for you mail account(s)? I have had no problems at all on laptops where I use IMAP, but I get the very high CPU usage on an old desktop where POP3 is used for mail backup.

IMAP
For all my 3 account I used IMAP@mib2berlin said in CPU usage seems quite high:

Hi, I use Intel and AMD, specs in my signature.
The only solution I am aware of is to remove the accounts and add it again.
Or the other way around, create a new profile and add one account, test this, add the next.
If this work you can switch this new profile to your default profile later.Cheers, mib

Thank you. I appreciate your time to solve my problem!

Just bumping this topic since I recently noticed that even my gaming laptop has high CPU usage with Vivaldi and mail activated! Whenever I close Vivaldi it is noticeable that the fan stops about ten seconds later. Tests shows it's at 20% CPU just idling... but is at 2% CPU if I use a guest profile without mail.
Since others mentioned AMD, I note that both this recent laptop and the old (15 years now!) desktop at 60% CPU are running AMD processors.
My wife just got a new laptop with Intel processor, so I'll see if it's the same behaviour there...
-
@mossman confirm that on my wife's new Intel laptop with the same profile and mail setup it's idling between 0% and 1%.
It's also idling 0%-1% on this 10-year-old work laptop with the same setup on Vivaldi snapshot - with the addition of a load of newsfeeds... also Intel.
So there's absolutely some bug in the mail system( * ) which has to do with AMD processors!
( * ) edit: or maybe Vivaldi/Chrome in general since 2% CPU without mail is still high for a much more powerful machine... maybe it's not noticeable in normal Chrome use but something in mail really relies on the affected subsystem.This topic has been discussed a few times over the last couple of years - does anyone remember if it was submitted as a bug? It should be! Otherwise I will submit a bug report in a couple of days...
-
@mossman (and in the meantime I'll have to turn mail on/off on the affected machines - especially for the gaming laptop where I can increase battery life and reduce heat & fan noise...)

@mossman this is not just AMD CPUs I think, about 2 years ago I had the issue with an INTEL CPU. We have this thread and another one running concurrently, in the other thread it's mentioned that the bug is reported as VB-99127 which is still open and unconfirmed because reproducing it by testers hasn't succeeded yet.

https://forum.vivaldi.net/topic/84788/mail-calendar-feeds-hogging-cpu/26?_=1724756928734Surprising that it's not been reproduced - unless I'm very unlucky that it affects two machines I use a lot and both happen to be AMD processors... yet on the Intel machines it doesn't happen at all.
(it's not due to profile corruption etc. since one is only a year old and mail was recently added on the other, also it was the same when I added mail to my wife's profile)
