While the slider lets you pick between just 1GB and 16GB on a system with 16GB of RAM, Microsoft warns that “setting a low limit may impact browser speed.”

Boooo, let us set it to zero you cowards.

I can’t wait to witness the chaos of Edge trying to handle my 100-plus tabs on just 1GB of RAM.

I too am keen on watching edge suffer.

This is the best summary I could come up with:

Microsoft is working on a new feature for its Edge browser that will let you limit the amount of RAM it uses.

The RAM slider appears to be targeted toward PC gamers, as there is a setting in Canary versions of Edge that lets you limit the amount of RAM when you’re playing a PC game or all of the time.

It’s not yet clear when Microsoft will ship this feature, as it’s only in testing in Canary versions of Edge right now.

The RAM slider is also available in the browser essentials section, which includes the power efficiency mode for Edge.

Microsoft introduced the power / performance mode for Edge years ago to improve the RAM, CPU, and battery usage of the browser.

How about zero?

What a stupid idea. Unused memory is wasted memory.

If someone is that limited by how much memory they have available, they can install more of it, close a couple of unused tabs, or exit one of the many bloated run-at-start-up game launchers.
