Improve performance in Vivaldi



  • @xyzzy Yeah, wouldn't that be nice?

    Though it's quite miserable in comparison to the V [/chromium] TM, i'm still jealous of Firefox's ability for its TM to run natively in a tab, thus allowing me to keep it pinned & readily fast-accessible in Tree Style Tab. Mind you, try as i might, i still cannot get its TM to then show up in Open In Sidebar, like "normal" tabs can. Thus re TM one might say that FF is ahead, but IMO only very slightly so [indeed, its inability to column-sort is a large reason i rate it "miserable", notwithstanding its "tabability"].



  • @chiller84: Keeping the OS updated is one thing.



  • Use private windows or guest windows for things that are only of temporal interest - reduces the cache size of your main install

    Disable each Web Panel which you don't use by right-click > Panels > remove the check mark (they stay loaded after first use)

    Good tips - thank you!

    Also just noticed for the second one that if you right click in a blank (unused) area of the Web Panel, you get a slightly different display which omits the extra step of the "Panels" sub-menu.



  • Some of these are puzzling to me, like "Use buttons in range controls." How much could that possibly matter? I would hope very, very, very little.

    And here's a bonus tip (not pertaining to memory, but performance): don't let the Favicons file exceed about 10MB if you use bookmarks.

    But my main question is about parsing this, as it brings up several related questions:

    Regularly delete Your Cache and Browsing History. Your cache is meant to speed up browsing by storing pieces of websites locally to load the page faster when you return. But if it grows too big, it will hinder performance because the browser has to dig through your cache to find the right files. Only remove the Temporary Internet Files.

    1. I get the cache part (though it shouldn't pertain to memory usage, right?) and agree that it's important to keep under control, perhaps more so than the Chromium core does by whatever secret formula it uses. But if it's that important, why hasn't Vivaldi added a size control for it yet? It is possible in the Chromium world (see Slimjet).

    2. "Only remove the Temporary Internet Files"? As opposed to what? The cache is Temporary Internet Files, but the latter is simply Internet Explorer's name for cache. Not sure why it's mentioned in this discussion, especially since you just recommended also removing Browsing History.

    3. Browsing History is a whole separate thing and is valuable to have. It's lumped in to the same paragraph, but I would hope that it's not as relevant (and if it is, are we talking about memory usage or performance?). Unlike Cache, Vivaldi does have an automatic, refined control for that one.

    4. "Delete Browsing Data" in Vivaldi doesn't list the sizes of anything, unlike chrome://settings/clearBrowserData. This often makes me wonder why Vivaldi implemented their own version if it was going to be a step down.

    No, disk usage. I have about 300 MB in cache, search a 300 MB database need time.
    I noticed that on my older laptop, today I use SSD on all devices and a fast CPU and RAM does not hurt either.
    There is no size control only time control, hours, week, months, year, all time.

    May it meant Cookies, Host App data and so forth.

    I have over 8000 items in Browsing History, same as 1.

    "Delete Browsing Data" in Vivaldi doesn't list the sizes of anything, unlike chrome://settings/clearBrowserData. This often makes me wonder why Vivaldi implemented their own version if it was going to be a step down.

    Use chrome://settings/clearBrowserData in Vivald or search in vivaldi://settings for "clear browsing".

  • @jacekn: Yeah, I frequently have this issue as well. It seems like this starts cropping up after the total number of tabs I've opened and subsequently closed starts to get very high. I've also seen rendering threads in my OS task manager jump to 100% and not come back down in relation to this.



  • I wish task manager provide more details on each vivaldi processes. Is it possible to give details of the tab you have open in task manager? Or show the name of the extension in task manager


  • - Ambassador -

    @archive1 Use Vivaldi's task manager (Shift+Escape), not the Windows task manager (Ctrl+Shift+Delete).

  • I love Vivaldi, use it on Mac, Windows and Android, but I'm having a hard time resisting to the enchantment of Edge. It is crazy fast.
    Is there any incoming major update that will address performance?



  • Hello.

    I really don't want to change, since I love it and I use it in windows, mac and Android, but Edge is so fast right now.
    Please focus on performance.

    @njjl Vivaldi devs always have an eye on performance. That said, if speed is your primary concern, you will have to use a rocket sled rather than an XUV. Vivaldi can never be a built-in, integrated app using all native components, because it is not installed in Windows by default like Edge.

    In spite of that, since Vivaldi can be completely customized to my workflow, it saves me tons of time every day and week. Edge cannot do that, no matter how "fast" it gets.



  • @Ayespy I never understood the people going on about how fast another browser is...

    Not only is my experience like yours, that the UI etc. makes the overall browsing faster than the clunky interfaces of other browsers, but I genuinely can't notice that Vivaldi - rather than network response or hardware limitations - is slowing anything down... ever.

    Literally the only time I've felt like Vivaldi is "being slow" was on the old netbook which had 1GB memory and no swap file... so that was quite obviously down to the system. The only fault of Vivaldi in that case was that it might be less lightweight than another browser (although I doubt that as well).

    @mossman I only have a 25Mb/s connection, so it can only fetch data as fast as it can. That said, on this box at least, Vivaldi is fluid and fast, and there is never any waiting for anything - at least none that I can notice.

    That may be down to having fairly good processor speed and RAM, so I don't begrudge anyone noticing a performance difference when using an integrated browser. I just did a side-by-side test of a local government website in both Vivaldi and Edge, and it appears that Edge finished displaying the website about a hundredth of a second faster than Vivaldi (no joke, about a hundredth of a second).

    Now on slower, less capable hardware, it might have been a full tenth, or even up to a half a second. This could still never compete with the time I save by having everything conformed to my workflow. So for my part, at least, I will settle for real time saved over the visceral satisfaction of having my every request filled instantly. The gamer crowd is addicted to thousandths-of-seconds-shaved-off performance, but my drug is money-made-in-a-day.

    I don't even know how you noticed that difference, and such a difference is definitely inside the margin of error of network congestion. Just for reference, the blink of an eye is typically referenced as a tenth of a second. Visually, it's really hard to see who won a race in running or swimming if the difference is just a few hundredths of a second. It requires very fast cameras and the recording played back in very slow motion.

    @BoneTone Biologically, the refresh rate of the human eye is 25fps for all intents and purposes. I can tell the difference between 1/10th of a second an 1/25th of a second. It was less than 1/10th, so perhaps I should have estimated 1/25th. Of course studies have demonstrated the human brain can extract meaning from an image in as little as 13ms, so while the eye can only refresh at 40ms, it would not be surprising to learn that the brain can tell when a stimulus is present for only a fraction of the refresh rate.



  • @Ayespy Still, I would expect the spread of the loading site, say, 25-100 loads of the same page of significant size to be greater than even double those 13ms. Making such a difference statistically meaningless.


  • Moderator

    @BoneTone Maybe so. I only ran it three times - a different page on the same site each time, and each time Edge finished almost imperceptibly faster. Three was enough for me to conclude it could be an actual difference between the browsers.



  • @mossman said in Improve performance in Vivaldi:

    My hypothesis:

    A statistically-significant majority of the posters who tediously have banged-on about this over the life of the Vivaldi forum, will go on at middle-age to purchase a red sports coupe & wear heavy gold chains around their neck.

    I have another theory too, btw. It involves the brontosaurus...



  • @Ayespy But Performance and Speed are two different things!

    I can complete a task involving multiple actions (performance) much quicker in Vivaldi, even if individual page loading is slower.

    @TbGbe That was, of course, pretty much my point. 🙂
