on my work PC at the moment (lovely little AMD 5700u mini-pc with 16Gb ram) I have a debloated LTSC build on W11 and two profiles of firefox running with a total of 25 tabs, a couple of them are more complex web apps but most are static pages, plus a couple of file browser, an old dumb custom invoicing app we use (~2003 application so its very light) and a VNC viewer with another machine running.

7.9gb of ram use.

it’s not that bad really, I mean it’s a lot for just mostly websites but we know they arent as light as they used to be, 8gb would be too little since I need some dedicated for Vram as I run 3 displays but I certainly dont need much more than 16.

I did have 32gb in this machine at first since I was doing some light photoshop and basic CAD/CAM, but it very rarely exceeded 16gb, so I cut it back and it’s been absolutely fine.

If you give windows more ram, it will use more ram as a baseline of course, unused ram is wasted ram.
