Extremely slow performance since upgrade

@robinmcarp
Hi, I understand your frustration but if only a few user have this issue and all other user not it cant be Vivaldi alone.
Imagine if all Vivaldi users had this, the forum would explode with posts, but that's not the case.
We try to erode why this happen for some user to make a valid bug report.
The Vivaldi developer cant fix "Vivaldi is slow".

Something I've noticed is that performance really suffers when opening images in new tabs specifically. The task of that new tab plus the GPU process go through the roof on the "idle wake up" values any time I click to open an image in a new tab. Over 1000 for each process that spike then slowly settle down.

This process is very slow: Choose image to open, middle-click to open in new tab, Ctrl+Tab to switch to new tab.

Hi, something is blocking Vivaldi on your system.
Open a complete bookmark folder with 20 tabs need 1-2 seconds to open all tabs.
Ctrl+T need 2/10 of a second.
It seems we cant find out why this happen for some user.

@mib2berlin
Both operations took 15-17 seconds to complete

But if I reboot Vivaldi it works no problem, for a while. Again, never a problem until this new build.

@pfine
Hi, a user post a command line switch, it solve many issues fore him to add this to the Vivaldi desktop shortcut.
--disable-features=UseEcoQoSForBackgroundProcess
Add it like here in the example:

Thanks, found that too and am trying now!

@mib2berlin Thanks for sharing.
I'm going to try it myself. At first sight, it's faster.

to be confirmed over a much longer period

FYI: adding a parameter in a Windows desktop shortcut does not run Vivaldi with the wanted parameters when started from other programs.

Not for unexperienced users: Such value should be added change should be done in Windows Registry Computer\HKEY_CURRENT_USER\Software\Clients\StartMenuInternet\Vivaldi....\shell\open\command and then for entry (Standard).

@DoctorG starting to think is a chromium bug. Why they didn't make a experimental flag is quite a mystery.
Desktops likely shouldn't need this mode.

I activated the --disable-features=UseEcoQoSForBackgroundProcess option last night, and it's much smoother. I didn't experience any huge slowdowns or after a while. Before, it was unusable.
even when I first launched vivaldi, I found it smoother.

I wish I would have read all these complaints before I updated to this "faster" version of V! The delay is absolutely ridiculous. Opening Vivaldi literally takes over 30 seconds for the white V screen to go away, and it's a full 2 minutes later and my laptop is still maxing out on the CPU. Thats with 1 window, 50 tabs total spread over 3 workspaces, no third party ANYTHING. The only thing that changed was the update install.

I'm on Windows 10 with no tab stacking or workspaces enabled, and Vivaldi comes to a crawl 12 hours after opening with only 10 tabs open. I have an Nvidia Geforce RTX 3080 Ti and an AMD Ryzen 9. At first I thought this was due to an incremental game I was playing when the issue first occurred, but the current tabs open are mostly static pages with no rapid changes. Nothing CPU intensive. Sadly the "fix" above is related to a feature exclusive tor Windows 11, so that can't be the culprit.

This also affects other parts of the browser, like the File menu and the Bookmarks panel, which become extremely slow to load after 12 hours (about 5-10 seconds).

@jaunny @oldbushie
Hi, the main difference of this build is the Chromium change from 114 to 116.
The "faster" influence only the performance to open new windows, nothing else.
I run tests with 700 tabs over a week and there was no slowdown at all.
Starting my Windows 10 on a VM to test Vivaldi 6.2.3105.51 with 100 tabs for some time.

I think this is a common problem with the Chrome engine since its appearance, remember the performance and use ram of the Presto engine with hundreds and thousands of browser inserts

oldbushie

@mib2berlin To clarify, I've been having issues since the initial 6.2 release.

@Volick
Hi, Vivaldi run fast as hell even on my aged laptop, if Vivaldi is slow something is wrong.
The usual subjects are third party security software and extensions.
@oldbushie
Did you check my link from the first page?

Cheers, mib

oldbushie

@mib2berlin I'm not sure which link you are referring to, I don't see any there. As for antivirus, I use Kaspersky currently. And all my extensions are site-specific. The only one that is on most of the time is Gmail Check POP3 Mail Now. The other 4 are for Reddit, Youtube, Facebook, and Twitter, none of which are sites I leave open overnight.

@oldbushie
Oh I am sorry, it was page 3:
https://forum.vivaldi.net/topic/90300/extremely-slow-performance-since-upgrade/25?page=3#:~:text=Hi%2C a user post a command
Is this Youtube enhancer? Some user report issues with this one.
No idea about these social media extensions, I use web panels for similar pages, chats and so forth.
The main problem with Google extensions is they are developed and tested with Chrome.
Many work fine in Vivaldi but in my experience from the forum over the Years they also cause 80% of all reported issues.
A user report he/she has to whitelist Vivaldi in Kasperky to get it running smooth again.
This happen often after an update of Vivaldi, the AV software "think" Vivaldi is alien and check each process.

Cheers, mib

I haven't read all these comments, I just previously posted my complaint about performance with this update. I'm no techie, but mib2berlin was able to resolve my issue with speed by suggesting I enable Lazy Load tabs. Just thought I'd post in case that helps somebody

oldbushie

@mib2berlin I added that command line option and added an exclusion for Kaspersky, but it still slows down horribly overnight. It took 15 seconds to load my bookmarks this time.
