Microsoft Edge Settings and Flags to boost performance : Part 1

Microsoft Edge on Windows 10 is great....but...can be slow sometimes.

Here is a word doc version of this post:

Here is the original post

Summary

For me Edge Chromium on Windows 10/11 is an exceptional alternative to Chrome & integrates nicely with Office365, however it can get slow over time. For me on my SurfaceGo 1.6Ghz *GB Ram tablet this was especially the case. Below is a list of tweaks applied to boost the load time, execution time, cpu usage and RAM usage of the Edge Chromium browser on windows. Many settings can be utilized with Chrome to, just replace edge:flags with chrome:flags and seek the flag name. Some settings are platform specific such as the new Startup Boost feature from MS for Edge, if I had time I noted otherwise please be aware.

Settings

1. 1.Sync: Sync only whats needed, turn off sync when not neede

2.       Flags: Browse to edge://flags/

3.       edge://flags/#enable-lazy-image-loading = enabled
4.       edge://flags/#enable-heavy-ad-intervention = enabled
5.       edge://flags/#enable-lazy-image-loading = enabled
6.   edge://flags/#enable-heavy-ad-intervention = enabled
7.   edge://flags/#allow-previews = disabled
8.   edge://flags/#disable-accelerated-video-encode = disabled
9.   edge://flags/#disable-accelerated-video-decode = disabled
10.   edge://flags/#enable-quic = enabled
11.   edge://flags/#lite-video-default-downlink-bandwidth-kbps = enabled
12.   edge://flags/#back-forward-cache = enabled
13.   edge://flags/#edge-experimental-tracking-prevention-features = enabled

14, Others:

edge://flags/#lite-video-default-downlink-bandwidth-kbps = 400

and

edge://flags/#quiet-notification-prompts = Enabled

15: Settings: edge://settings/system

16: New Performance Mode:

--enable-features=msPerformanceModeToggle

1. First of all, right-click on the Edge Canary desktop shortcut and select “Properties”.

2. Navigate to the target field in the Shortcut tab, add a space, and then paste the following parameter: --enable-features=msPerformanceModeToggle

3. Click the Ok button and restart the browser to apply the latest changes.

4. Finally, head to Settings >> System >> and enable the “Performance Mode” toggle button available under the Optimize Performance section.
