The way to make Edge run way faster is to edit your hosts file. This is a neat, simple trick I recently learned that I've successfully accomplished with no issues whatsoever on two machines. As long as you follow the instructions there won't be any issues. Below these instructions is a link, which will automatically download a community hosts file to your Downloads folder. You could write your own hosts file, but this is very time consuming and this community hosts file is well know and is constantly updated.
To put it really basically, websites have to go through your hosts file before they're presented on your PC. I won't go through it all, but if you add a website's or ad-server's URL to your hosts file with your local IP address in front of it (this is always 127.0.0.1) then instead of connecting to the website or ad-server your computer attempts to connect to itself and thus shows nothing at all. This is different from an ad-block because it is system wide, meaning it affects all browsers, applications, and programs. It's also faster and more secure because the websites or ad-servers never actually reach your browser. You can also customize it and add any URL's you want. With this community hosts file installed (the link below) Edge is actually faster than either Chrome or Firefox. Make sure to follow all of these instructions, as if you're not careful, you can do some serious damage to your system. Never edit your default hosts file.
[To backup the default hosts file]
Run Command Prompt as Administrator (Click Start Menu, go to All Apps, go to Windows System, right click on Command Prompt, select Run as Administrator)
Type "cd\"
Type "cd Windows\System32\drivers\etc"
Type "dir"
Type "Copy hosts c:\temp"
[NOTE: Do not type the quotations marks]
[To view and/or edit hosts files]
Run Notepad as Administrator (Click Start Menu, go to All Apps, go to Windows Accessories, right click on Notepad, select Run as Administrator)
Select File>Open
Navigate to hosts file (default is found in C:\Windows\System32\drivers\etc)
Select All Files (hosts files aren't text files)
Open the correct hosts file
Make necessary changes
Save (do not press Save As, as this will save it as a text document instead of a file)
[Note: The default IP Address is 127.0.0.1]
[Note: To add websites to your hosts file, simply type your default IP Address followed by the website URL]
[Note: Make sure to backup your default hosts file before making any changes]
[To replace the default hosts file with the new hosts file]
Navigate to the new hosts file
Copy new hosts file to desktop
Navigate to C:\Windows\System32\drivers\etc
Rename hosts to hostsOLD
Copy the new hosts file from desktop to the hosts folder
Restart browsers
[Note: You could use the .bat in the community hosts folder (that you downloaded) but it's not necessary as you can just do the way depicted above]
[Note: You do not have to reboot your computer, as any changes to the hosts file are immediate changes]
[Note: If you do need to force your computer to read your hosts file, simply navigate to the Command Prompt as Administrator (as depicted above) and type "ipconfig /flushdns" without the quotation marks]
[To shutdown DNS Client (mandatory with hosts files larger than 135 kilobytes)]
Win+R to open Run
Type services.msc
Scroll down to DNS Client, right click, and select Properties
Select Stop
Click the drop-down arrow for Startup type
Select Manual
Click Apply/OK and restart
[Note: Make sure to turn DNS Client back on if you revert to default hosts by following the above steps and changing the startup type to automatic]
[Note: You will have to shut down the DNS Client with this community hosts file]

[Note: The hosts file that your system recognizes is the one called "hosts" or "HOSTS" without the quotation marks. You can keep all your hosts files (you can have more than one, but only one active hosts file) in the same folder, as long as only one is called "hosts" without the quotation marks. For example, you can a hosts file that blocks Facebook and a hosts file that doesn't. The hosts file that's active (let's say the one that blocks Facebook) will be called "hosts" without the quotation marks and the hosts file that's not active can be called anything else like "hostsFB" without the quotation marks]
I believe that's everything you need to know.
