High hard disk activity by Vivaldi 1.0

  • Vivaldi Translator

    Today I'm experiencing lots of hard disk activity that is probably caused by Vivaldi 1.0.435.42 () (64-bits) (and also the previous 1.0 version) SysInternals Process Explorer attributes the high load of hard disk IO to Vivaldi. When I close Vivaldi, Process Explorer shows that most of the Vivaldi processes are shut down except for two that remain active (and keep up the hard disk IO load) When I order Process Explorer to kill the remaining Vivaldi process tree, the hard disk IO activity slows down to low levels. I hope this can be reproduced. Is there a log file that I can dig up and attach to this report?

  • Here too, I'm experiencing the same as you, after exiting Vivaldi I need to end task in Task manager and the disk usage slows to normal.

  • Same here in 1.1.443.3 32 bit and in the last, probably 3 versions.
    Make using Vivaldi unpleasant

  • Yes, cpu usage is high, my fps drops to 0 when loading sites.

  • The same here with last versions of Vivaldi and Win 10. It is frequently using 100% of my SSD… until I close the process.
    I believe it is related to the loading of thumbnails. I reported that on the bug tracker.
    I don't use Vivaldi anymore, I don't want to destroy my SSD !

    I will try your trick Sajadi.

    Edit : I deleted the both "top sites" files and... YES, it worked ! I can reload thumbnails without problem now.
    Thank you Sajadi !

  • I had the issue today as well and deleting the top sites fixed it for me.

  • All thumbnails disappeared today and the problem came back with SSD at 100%.
    I could fix it by removing the "Top Sites" file again. Very annoying.

  • Does someone has a bug number we can use to report in the blog? Thanks!


  • Yes : VB-16139
    The problem hasn't occured again on my computer since RC3 / Stable 1.1
    And other people ?

  • Finally, it isn't resolved on v1.1 : I had this bug again today.

  • Issue is still here as described by previous commentators.

    Vivaldi: 1.2.479.8 (Developer Build) (64-bit)

  • Unless it is not running then Vivaldi never has and never will stop writing to disk. The team has done a fantastic job taming some of the more outrageous behavior but it is a busy browser.

    Here is one quick moment in time with Vivaldi and Windows nattering something about cookies and the LastPass Extension while the NTFS tries to keep up with the constant changes:

  • Experiencing the same high HDD activity! I am using Vivaldi 1.4 on Windows 10.

  • @Sajadi:

    You can try to delete the 2 files "top sites" and "top sites-journal" from your profile directory, a friend had a similar experience and fixed it by deleting that 2 files.

    Also, deactivate hardware acceleration inside the browser this could also fix such issues. You can find the setting under the following url:


    Btw. in case if that url does not work as it should please try:


    I'm having the same problem. Where is the profile directory?

    Look at Menu/help/about. There is a line there with the title "Profile Path." That tells you where it is.

    Thanks, but I followed the path, leading to Vivaldi. Right clicking didn't show a 'profile path'. I'm not good at techie stuff, so I maybe missing something.

  • IGenius– maybe this post will help you? It made things a little clearer for me, about the profile issues.

    If you are using the red "v" in the square button at the top left of your browser as your menu, click on it.
    When you do, options will appear, and the last among these will be the word Help.
    If you are using the horizonal printed word menu across the top left of your browser, just look at it.
    At the end, you will see the word Help.
    Click on the word Help.
    When you do, you will see a list of options and the last of these will be the word "About" with a Vivaldi logo in front of it.
    Click on the word "About."
    When you do, you will be taken to a page with a bunch of information about the browser.
    The second to last line on this page will begin with the words, in bold, "Profile Path:" It will look something like this:
    Profile Path: C:\Users\USER\AppData\Local\Vivaldi\User Data\Default
    That path is where your "Default" folder lives. You see at the end of the path, the word "Default."

    Now if you're not a techie, or just basically know nothing about computers except how to work the power switch, the keyboard and the mouse, this won't help you much and you should probably go no further. Just forget about it.

    If, on the other hand, you can find and copy and rename files on your own machine, you should make sure that at some point you have gone (in Windows) to the Control Panel and made use of the Folder Options or the File Explorer Options (depending on your version number) and set your system to be able to show you "hidden" files and "protected system files."

    If so, you are ready to follow the path shown to you in help/about/profile path. Using the profile path I just showed you above, here is how you would do that.

    Open "This Computer"
    Double-click on the C: drive
    In the list of folders on the C: drive, scroll down and click on Users.
    In Users, you will see your own User Name. Click on it.
    This will reveal a list of folders, and early in that list will be one called "AppData."
    Click on that, and there will be a bunch more folders. On is called "Local." Click on it.
    Inside Local is another bunch of folders, and one is named "Vivaldi."
    Open it.
    Inside Vivaldi are two folders - Application, and User Data. Open the one called User Data.
    In it, there is a folder named Default.

    You are now in position to follow the instruction in the sticky post regarding how to refresh your profile.
    Good luck.

  • You don't need to do any of that. 🙂

    Just open any folder, then click the address bar so the graphical representation of the path becomes a text field, and you can just copy and paste whatever path the Help > About said was the profile path.

    You know that. I know that. But what would a person doing that learn about the actual structure of the system they are messing with? Nothing. I wrote it so that anyone trying to do it would learn something about the "machine" they are working on, and could always retrace their steps, because they knew where they had been.
