How to speed up the Opera web browser

The following guide provides you with information on how to speed up the Opera web browser to improve performance and your overall experience.

The "new" Opera web browser is a Chromium-based browser that shares much of its code with Google Chrome. While I have not seen many complaints about the performance or resource use of the browser, there is always room for improvement.

The following tips may help you get the most out of Opera. It may be especially useful if you run Opera on a low end system with little RAM and a weaker processor.

Speed up the Opera web browser

opera performance settings

First thing I suggest you do is go through the preferences of the web browser. This approach is the same that I used for the guide on improving the Vivaldi browser's performance.

Load opera://settings/ in the browser's address bar to get started. You may want to enable the "show advanced settings" and "always show power user settings" options on the Settings page.


opera browser settings speed up

Select Browser on the Settings page. Make the following adjustments to it:

  • On Startup -- make sure Delay loading of background tabs is enabled. This improves the startup of the browser if the previous session is restored on start.
  • Shortcuts -- If you don't use gestures, disable "enable mouse gestures" and "enable rocker gestures".
  • Personal News -- If you don't use the personal news feature, set the "check my sources for new content" value to never. Disable "show available news feeds on address bar" if you don't require it.
  • User interface -- Disable "show tab previews" and, if you don't use it "enable the search pop-up when selecting text".
  • Themes -- Select a basic theme, e.g. the white background.
  • Battery Saver -- Battery Saver preserves battery when you are using Opera on a device on battery. It will reduce performance however to achieve that. If performance is more important to you, disable battery saver.


opera website settings

The tweaks under websites depend largely on how you use the browser.

  • Images -- If you can live without images for the most part, consider switching the setting to "do not show any images". This is not recommended for most users, but will improve page load time.
  • Flash -- Make sure Flash is either set to "click to play", or "block sites from running Flash". You can add exceptions for sites that you want Flash to run on.

Privacy & Security

Settings depend large on usability here. You may want to consider enabling ad blocking, and disabling the following options under privacy:

  • Predict network actions to improve page load performance.
  • Help improve Opera by sending feature usage information.
  • Automatically send crash reports to Opera.
  • Fetch images for suggested sources in News, based on history.

Other Tweaks and options

opera task manager

One thing you may want to do is open the built-in Task Manager to monitor memory and cpu usage of the browser, extensions, websites, and the gpu.

It may pay off to keep the Task Manager window open while you use Opera like you would normally. Doing so may reveal bottlenecks or issues, for instance with installed extensions or sites loaded in the browser that impact the browser's performance and speed.

Opera, since it is based on Chromium, supports the same startup parameters like Chromium, Chrome or Vivaldi for the most part.

The following startup parameters may improve the browsing performance. They are the same that improve the speed of the Vivaldi browser.

  • -process-per-site switches from a process per tab model to one that is lighter on resources by bundling all pages of a site into a single process. This saves you memory if you open multiple pages on the same site regularly.
  • -disk-cache-dir=z:\opera\ –disk-cache-size=104857600 moves the disk cache to another drive, and sets it to 100 Megabyte. Especially useful if moved to a faster drive, or a RAM disk.
  • -enable-low-end-device-mode improves memory consumption by making tweaks that benefit lower end devices the most.
  • -enable-low-res-tiling improves performance when scrolling on low end devices.

While you may run Opera with these parameters manually, you may want to add them permanently to the browser's shortcut to improve usability.

You have to right-click on the Opera icon in the taskbar on Windows (or Start Menu, or Desktop), and either select properties right away, or right-click on Opera again before properties becomes available.

Add the startup parameters to the end of the target field, and make sure that there is a space between Opera's file path and name, and the parameters.

Here is an example: "C:\Program Files (x86)\Opera Developer\launcher.exe" –enable-low-end-device-mode

    Hi Martin, are there parameters for the Slimjet Browser too? Or do the parameters above work with Slimjet as well?

    1. Martin Brinkmann said on February 14, 2017 at 2:03 pm

      Any Chromium-based browser likely supports most of the parameters. I have not tried Slimjet, so cannot say if this is true.

      1. Thorky said on February 14, 2017 at 8:22 pm

        Thanks, I will try some Chrome-Parameters on my own. :)

  2. MdN said on February 14, 2017 at 12:20 pm

    I love this –process-per-site thing, just what I needed for my RAM and browsing habits. Thanks!

    I can’t understand why opera closing so slowly? Any ideas?

    1. Alex said on February 25, 2017 at 9:51 pm

      Maybe you have an AddOn syncing before close?
      If is not the case, you may find more answers in

    Is it possible to do the process-per-site thing on the macOS version as well?

    1. MdN said on February 15, 2017 at 12:39 am

      Probably. I did it on Linux so it should be the same. Try it and check the task manager (here it’s Shift + Esc) to see if it worked.

  5. Justin said on February 14, 2017 at 11:27 pm

    Cent browser is very fast.

  6. DigitalD said on February 24, 2017 at 9:06 am

    correct parameter is “–”

    C:\Program Files\Opera\launcher.exe –enable-low-end-device-mode

    not like:
    C:\Program Files\Opera\;launcher.exe -enable-low-end-device-mode

    did u copy and paste it from another source? did u try it by yourself?

  7. D. said on March 17, 2017 at 1:32 am

    Thanks Martin…

    I can’t find “always show power user settings” option in O46.0.2567.0.

  9. Orinocco said on September 6, 2017 at 1:53 am

    Hi, i can’t find how to adjust the size of the internet cache,history, its huge, way bigger than Firefox and takes ages to clean, i have the latest Opera, but whereas in Firefox you can override the automatic cache, i can’t see if its possible in Opera.

  10. John Lomonaco said on November 30, 2017 at 3:55 pm

    I was referred to this web page from the Opera Forum when I inquired about ways to make my old XP machine run the browser faster. I tried the tweaks suggested that I thought would help and they did. Its not a speed daemon but it runs much more acceptably. Thanks.

  11. Andrè M. Pietroschek said on March 10, 2018 at 10:50 am

    Thanks for your hints, and sorry I cannot donate you some money.

  12. Zoran said on May 10, 2018 at 6:56 pm

    Thank you very much for help!

  13. Eric Malhan. said on July 21, 2018 at 7:17 am

    I have following the tips above and now? After short time Opera keeps still very slow.
    So it was waisting my time to try to make an solution of this.
    Opera is and stays very very slow.
    I hope there is an better solution for this.

    1. dan3952 said on November 10, 2018 at 8:30 pm

      It’s your connection. No amount of tweaking will help you, and all of your browsers will be slow. Please don’t criticize innocent people who have spent their spare time providing helpful suggestions.

  14. Jaelyn said on May 8, 2019 at 1:50 am

    Wow. after making only three or four changes opera started running better. I’ve made several more and it’s like a new browser.
