Vivaldi noticeably sluggish since upgrading to 3.0



  • @neonturbo
    I have not such a performant system like yours, i5 3570K 16GB, and there is no difference performance wise between Vivaldi, Opera and Chrome on it.
    May we can find out why, I love such problems but hate them at the same time.

    With AV software I meant anti virus software, some user report problems with Vivaldi (even Defender).
    My last idea for now, disable it for a test.

    The screen cast need a lot of power, it is much faster without.



  • In an attempt to figure out why my seldom-used Vivaldi Dev install doesn't have the issue (as far as I've seen in testing), I took a look at the largest files in the profile of my main install (which are all much larger than their equivalents in my Dev install) on the theory that 3.0 has developed a sensitivity to profile files of a certain size (this wouldn't be a new phenomenon):

    77MB: History
    17MB: Bookmarks
    8MB: Cookies
    3MB: Web Data
    2MB: Visited Links

    And this one, which after further reading around here, I found was a basically useless file:

    15MB: Top Sites

    So, I deleted it and have been re-testing without it (well, with its <1MB replacement). So far so good, but it's too soon to know for sure, and I rarely guess right on the first attempt.



  • @rseiler Cleaning up download panel history (via brush icon) and using "last 7 days" in history panel help too.

    Mine:

    • Bookmarks: 2 MB
    • Cookies: 2,8 MB (Cookies cleaned at startup)
    • Favicons: 23 MB (was 34 MB)
    • History: 98 MB (All history kept)
    • Top Sites: 51 MB (Is still 20 kb)
    • Web data: 1,4 MB
    • Visited links: 2 MB

    I'm not even sure the Top Sites is used.
    I tried to remove this. Now is 20 KB. We'll see.

    @neonturbo Do you observe the same issues with a clean profile or even a guest window?



  • @Hadden89 Thanks, I happened to clear the download panel yesterday (there was a LOT in it) and normally have the history panel on "last 7 days."

    Mainly posting to report that Top Sites is not the culprit, since I was just able to reproduce the problem (I'll look now at other suspects in the list).

    So, there might be some kind of threshold that's crossed after X hours of use (I've had Vivaldi open for 4 hours) where you're susceptible to the problem, or there's a specific action which enables the problem. But once you cross that fine line, I do have two wonderful test sites that will reproduce the problem every time.

    The first is on Amazon, on a URL like this, when you change the "Sort by" in the upper right. It will lead to a hang like this which stops Vivaldi dead for about a half minute:

    Capture.JPG

    The other is SurveyGizmo, of all things, which I noticed yesterday when attempting to fill out a real survey. This is just a demo one, but it serves the purpose, once you start to fill out the survey.

    And, I need to modify what I said yesterday about Ctrl+N (and Ctrl-Shift+N): they're not a total workaround. While the browser doesn't go into Not Responding, it does take more CPU than normal and slows down when on either of the above test sites (once you've crossed the mystery threshold--not normally). Basically, it gets through them a lot better than the main window does when in this state, but you still notice something isn't right.



  • I have observed what I believe to be similar behavior. Vivaldi 3.0.1874.33 on Windows 7 will freeze for about 30 seconds with full CPU usage of 1 core. Sometimes it can happen unpredictably, but it's also easily reproducible in Google Calendar when you click on an appointment to see the floating details bubble, or in the chrome://settings page when you click on a link like "Addresses and more" or any other of those wide center navigation buttons. I noticed that both of these UI elements seem to use Google's paper animations, so maybe there's something going on there.

    I tried looking at DevTools performance recordings for both the active tab as well as the packed Vivaldi app page, and both just show really long renders without any methods being called. The OS stack dump of the spinning thread just shows a ton of calls in ChromeMain, but I definitely don't have the symbols to know what it's doing.

    I determined that the problem was enabling Native Accessibility API Support and Web Accessibility in vivaldi://accessibility. When I disable Web Accessibility and Native Accessibility API Support, the performance problem is resolved. As mentioned previously in this thread, it did not reproduce in the last stable 2.x version of Vivaldi.

    I was using those accessibility settings because KeePass2's WebAutoType plugin uses MSAA (IAccessible) to detect the URL of the foreground browser window. I was launching Vivaldi using a small program that always added --force-renderer-accessibility to the arguments list to always enable MSAA in Vivaldi and allow this plugin to work correctly.

    @aldaviva please, can you report to bug tracker with a complete explanation?
    Vivaldi needs reports on such accessibility bugs in Vivaldi. #a11y #allyfirst


    Thank you for reaching and sorry for the trouble.

    May be this issue is a bug.

    Please read

    carefully and report the bug to Vivaldi bugtracker.

    Again thank you for using Vivaldi.



  • @aldaviva Thanks, though unfortunately in my case I'd never heard of that page, so that setting isn't enabled.

    Does yours display a "Not Responding" title bar when in the hung state?

    I haven't reported my version because, unlike yours, it's not in the problem state all the time, and I don't know how to get it there. I only know how to reproduce it once it's there, which is insufficient. I'll definitely be trying the two things you mentioned (Google Calendar, etc) once it's in the state to see if they also have an effect here.

    You saved my life because I had the same exact problem. And removing --force-renderer-accessibility removed the freezes completly. But I think this is a chromium bug because I had the same exact problem with another chromium based browser.

    Then please report that to Chromium bug tracker, they should fix it and Vivaldi can get the fix in a upstream. => https://bugs.chromium.org/p/chromium/issues/entry

    @aldaviva Please report that to Chromium bug tracker, the Chromium devs should investigate and fix, Vivaldi can get the fix in a next upstream i hope. Report at https://bugs.chromium.org/p/chromium/issues/entry

    @neonturbo
    Hi, the problem is it is not for every user only for a few.
    One user report he use 20000 bookmarks, it slows down Vivaldi to turtle.

    I've just recently switched to Vivaldi as a default browser purely for the native bookmark set up. It is the best I have come across.

    I am noticing quite poor performance from the browser, especially when compared to Chrome (or any browser). I only have 4 critical extensions installed (but it's also poor and laggy without them).

    I've been wondering what the issue is and now I'm wondering it might be due to the bookmarks. I only have about 50 so far but this will eventually rack up into the many hundreds easily.

    Thing is, I had hundreds in Chrome years ago when I used this as my default browser and it performed better than what I'm getting with Vivaldi now.

    It will disappointingly result in me switching back to Opera probably if performance is going to get even worse with the more bookmarks I add. 😞

    @zigojacko Several hundred bookmarks is not an issue here. It causes no noticeable impact. Twenty thousand would, no doubt.

    Recently, Vivaldi has changed how it treats individual windows as entities. It sped things up for me, and for many. One thing to consider would be whether it slowed things for others.



  • @rf10 said in Vivaldi noticeably sluggish since upgrading to 3.0:

    I disabled all extensions and no noticeable difference.

    So the issue with just disabling extensions is that it doesn't necessarily remove all influences from every extension. The best way to be certain that extensions are not involved is to create a new user profile and test with that.



  • @Ayespy said in Vivaldi noticeably sluggish since upgrading to 3.0:

    I missed this earlier, but unless some recent change has caused a regression in performance, 20,000 bookmarks is no issue to Vivaldi. I'm currently running with more than 6x that, and there are few if any areas where I notice performance problems due to the size of my bookmarks library. The only place I have run into issues is when loading the list of folders while editing a bookmark on Android, and then when saving a bookmark to a different location.



  • I'm also having problems with Vivaldi being slow and laggy - freeze when opening new pages, freeze when closing pages, freezes when scrolling pages. It's very annoying, and my computer is powerful (16GB RAM, GTX1060 MaxQ, i7-7700HQ). Disabling hardware acceleration may or may not have made a difference (not terribly noticeable, and it is undesirable to disable hardware acceleration).

    I posted about it here, will also open a bug report:

    Does it by any chance start happening after you leave Vivaldi idle for a prolonged amount of time?

    @NineWest The original fix described how removing the argument solved the issue for the user. Are you saying that your issues were fixed by adding the argument?
