System hacks: modify small parameters to make Edge faster

Microsoft started to install another Edge browser inside the Windows 10 system to replace the long-used Internet Explorer. However, many users feel that the speed of this browser is not as fast as the common Google Chrome or Firefox, so it has not been recognized by the majority of users. In fact, we only need to modify a few parameters that come with this browser to stimulate the potential of this browser’s Internet speed.

Start the new enhanced TCP protocol

First of all, let’s start Edge browser, type “about:flags” in the address bar and press the Enter key to enter the parameter modification window of the browser. After opening the parameter modification window, we can see two big options: “Developer Settings” and “Standard Preview”. In fact, we can also use the shortcut keys Ctrl+Shift+D to view the browser’s other hidden parameter options, here we will introduce and modify some of the more important options.


We usually use TCP and UDP protocols to access the Internet. Although the UDP protocol has the characteristic of fast transmission, the biggest disadvantage of this protocol is that it is easily disturbed by other factors. The disadvantage of this protocol is the advantage of TCP protocol, so in order to make the browser have a better Internet speed, the first step is to reduce the degree of interference with network packets. The “TCP Fast Open” is an enhanced version of TCP protocol, which can increase the loading speed of web pages by about 10% as long as both the browser and the server support this protocol. So here we find the “Network” option in the “Diagnostics” tab, and then select “Always Enable” in the “Enable TCP Quick Open” list (Figure 1).

Limit unimportant JavaScript

The most important factor for the speed of any browser is the rendering engine it uses, so it is important to set the parameters related to the rendering engine. For example, JavaScript is one of the most widely used languages inside web pages, and it allows users to interact with web pages in a relevant way.

However, active JavaScript can have an impact on the battery life of mobile devices, so users find that the power is constantly consumed when browsing certain web pages, which naturally affects the speed of web browsing. Therefore, you can enable the browser’s “Limit Rendering” feature. So let’s find the “JavaScript” option in the “Diagnostics” section and check the “Allow restricted rendering channels to extend battery life” box.


In addition, some web pages will pass a lot of JavaScript ads and traffic statistics scripts, which will also cause the mobile device battery power to decrease rapidly. So we can check “Allow background tabs to be in low power mode” in “JavaScript” to limit the CPU power allocated to background tabs, thus speeding up browsing and extending battery life (Figure 2). ).

Disable Microsoft’s compatibility list

As web technologies continue to evolve, websites need to adopt new technologies to allow users to navigate faster. However, some websites are still using older technologies, so in order to be more compatible with these websites, Microsoft has introduced a compatibility list. If a website is in this list, Edge browser will automatically adjust the code to display the page.


However, Microsoft does not specify when this compatibility list will be updated, so once a web page has adopted a new web technology, it will definitely slow down the user’s browsing speed if it is still on this list. The only way to solve this problem is to force this feature to be turned off, and users just need to remove the “Microsoft Compatibility List” option in the “Developer Settings” option (Figure 3).
