Microsoft Edge Slow

 



The problem: Your browser isn’t working. The time it takes for a page to load is way too long and it’s acting slower than a three-toed sloth.

What can you do?

To clear the browsing data to resolve issues on the Chromium version of Microsoft Edge, use these steps: Open Microsoft Edge. Click the Settings and more (three-dotted) button from the top-right. Microsoft edge not Responding. Microsoft Edge slow performance and Edge browser not responding These are common problems for all web browsers. If you face the same problem on chrome or firefox browser you can simply clear the Browser cache, old history, delete extensions etc. If still the problem persists simply uninstall the web browser.

While Microsoft Edge is one of the fastest browsers out there to date (reportedly faster than Chrome), it can sometimes be slow to load for one reason or another. Most browsers have their moments…

The good news? You can usually fix these kinds of problems yourself. And no, you do not need to be a technical expert to do this.

To help empower you in a moment of frustration when your browser is slow, here are the top 5 things you can do to speed up Microsoft Edge in Windows 10.

Microsoft Edge Slow After Upgrade

Start with the first task and go down the line until your browser’s performance improves.

  1. Check your internet connection (sounds obvious right? But it could be a quick fix!)
  2. Delete browser history and cleanup your cache and cookies
  3. Tweak browser flags (this is a helpful one!)
  4. Turn off background apps
  5. Delete or update Edge extensions

Check your internet connection

This is generally a good practice. Your browser might be slow simply because your internet connection is poor.

Step 1: First check to see that you are connected to Wi-fi by clicking the wireless network icon and selecting the appropriate network name.

Step 2: If you’re on Wi-fi, but the wireless connection is still slow or simply doesn’t work, you will need to run the Windows troubleshooter to diagnose and fix internet connection issues. Right click the wireless connection icon again and select Troubleshoot problems.

Step 3: Read and respond to the on-screen prompts.

Step 4: Check to see if the troubleshoot was successful. If it was not, it will look like the image below:

Step 5: At this point, it’s time to run Device Manager. Click on the Start button (or press Windows key + X).

Step 6: Type in Device Manager into the search bar and then select it.

Step 7: Expand Network adapters from the list by clicking on the arrow to the left of it. See below:

Step 8: Right click on your wireless network driver. The name of your network driver will show up in the drop-down options. From there, select the option Update Driver. See the example below:

Step 9: Click on the option that says Search automatically for updated driver software.

Step 10: Windows will now search the computer and internet for an updated driver. It will install one if it’s available. Relaunch Edge when this is complete and see if your connection has improved.

Step 11: If this doesn’t resolve the issue, reset your network settings altogether.

  • Try restarting your computer. You can also try unplugging the power cord from your wireless router and wait 10 seconds before plugging it back in.
  • Go back to the Start button, click on Settings, then select Network & Internet (or type this into the search bar). Click on Status then scroll down to the bottom and select Network reset.
Fix

Delete browser history and cleanup your cache and cookies

Let’s say the problem wasn’t your internet connection. Well, the next thing to do is clean up your browser data. Over time, your browser stores a lot of information about you that can actually slow down your browser’s performance.

Check out our previous Tech Tip that walks you through how to clear your browser data and safeguard your internet privacy. This can ultimately speed up your page load times and browser performance.

Adjust browser flags

If your browser is still slow, it’s time to turn to browser flags.

Browser flags are where you can turn on Edge features. And there are two key features that you should use to speed up Microsoft Edge: TCP Fast Open and low-power mode for background tabs.

Enable TCP Fast Open

Even though it sounds like a complicated term, it isn’t.

TCP is a protocol developed on the internet that basically just makes sure data gets to where it needs to go. And this particular extension can speed up the time it takes a page to load by 10% to 40%.

Step 1: Open Edge browser then type about:flags directly into the address bar. This takes you to a setup page.

Step 2: Scroll down until you see Networking.

Step 3: Check Enable TCP Fast Open.

Step 4: Restart Microsoft Edge and see if this speeds up your browser.

Enable low-power mode for background tabs

This is the next flag you can tweak. And what it does is basically limit the amount of CPU power (AKA your computer’s processing ability) that is given to open tabs that have A TON of JavaScript-heavy ads. This should speed up your browser significantly.

Step 1: Go back to the browser flags list by typing in about:flags into the address bar.

Step 2: This time scroll down to JavaScript.

Step 3: Check the box that says Allow background tabs to be put into a lower power mode.

Step 4: Restart Microsoft Edge again and see if your browser has improved.

Turn off background apps

Is your browser still slow at this point? If you’re still struggling and nothing has worked so far, the next quick and easy thing to do is just turn off apps that you don’t need to run all the time.

Step 1: Click on the Start button and go to Settings.

Step 2: Click on Privacy and select Background apps.

Step 3: You’re going to see all the apps that are running in the background. All you need to do is toggle off every app you don’t want to turn on automatically. This should help speed up your browser.

Delete or update Edge extensions

If you’ve made it this far and your browser is still sluggish, the last thing we recommend doing is to get rid of Edge Extensions you have installed (or update the ones you want to keep). We’ve noticed that common add-ons like AdBlock can sometimes affect the speed of your browser.

Step 1: Open Microsoft Edge and click on the three dots (…) found in the top right corner of your browser window.

Step 2: Select Extensions from the menu.

Step 3: Select each extension and click on Uninstall.

Step 4: Restart Microsoft Edge. See if your browser speed improves then go to the Microsoft Store and reinstall your favorite extensions if you still want them.

Hopefully, these tasks have significantly sped up the Microsoft Edge web browser on your PC.

However, if you are still experiencing problems, you may need to deactivate proxy settings on your Windows 10.

For more troubleshooting, we recommend contacting Techwise Group or your company’s IT department for help.

Microsoft Edge Slowness

-->

This guide shows you how to detect network issues or optimization opportunities in the Network panel of Microsoft Edge DevTools.

To learn the basics of the Network tool, navigate to Get Started.

Queued or stalled requests

Symptoms

Six requests are downloading simultaneously. After that, a series of requests are queued or stalled. Once one of the first six requests finishes, one of the requests in the queue starts.

In the Waterfall in the following figure, the first six requests for the edge-iconx1024.msft.png asset start simultaneously. The subsequent requests are stalled until one of the original six finishes.

Causes

Too many requests are being made on a single domain. On HTTP/1.0 or HTTP/1.1 connections, Microsoft Edge allows a maximum of six simultaneous TCP connections per host.

Fixes

  • Implement domain sharding if you must use HTTP/1.0 or HTTP/1.1.
  • Use HTTP/2. Do not use domain sharding with HTTP/2.
  • Remove or defer unnecessary requests so that critical requests download earlier.

Slow Time To First Byte (TTFB)

Symptoms

A request spends a long time waiting to receive the first byte from the server.

In the following figure, the long, green bar in the Waterfall indicates that the request was waiting a long time. This was simulated using a profile to restrict network speed and add a delay.

Microsoft edge slow download speeds

Causes

  • The connection between the client and server is slow.
  • The server is slow to respond. Host the server locally to determine if it is the connection or server that is slow. If you still get a slow Time To First Byte (TTFB) when accessing a local server, then the server is slow.

Fixes

  • If the connection is slow, consider hosting your content on a CDN or changing hosting providers.
  • If the server is slow, consider optimizing database queries, implementing a cache, or modifying your server configuration.

Slow content download

Symptoms

A request takes a long time to download.

In the following figure, the long, blue bar in the Waterfall next to the png means it took a long time to download.

Causes

  • The connection between the client and server is slow.
  • A lot of content is being downloaded.

Fixes

  • Consider hosting your content on a CDN or changing hosting providers.
  • Send fewer bytes by optimizing your requests.
