Question High Memory usage. Memory leak?

[VenusAmbassador]

Even immediately after restart, my memory usage is around 50-60% despite task manager showing nothing that could be taking up half of my memory. With firefox running, it's consistently at 85-90% usage.
I've run Poolmon and Rammap and included screenshots, if I empty working sets in Rammap, it seems to temp fix it (my usage drops to 25-30%), but it seems to creep back up to the 40-50% range (with firefox running) and after a restart it defaults back to before I emptied working sets.

This is with a clean install of win11, startup programs disabled, antivirus came back clean, and drivers up to date (dell and intel auto driver installer says everything's okay, I did try and manually install some it seemed I might not have, didn't help)

Specs:
Dell Vostro 3420

i5-1135G7 2.40GHz
Intel Iris Xe Graphics
8 GB Ram
256 GB SSD
Windows 11

8GB ram is what it is
firefox (31) would for sure want more ram than you have, unfortunately garbage collection has to be saving as much as it can to fit in

have you tryed having opened just a single tab? each tab has reserved 2GB ram, it will keep filling up once you start browsing

my concern isn't firefox using too much ram, it's that even before I start any program on my computer over half of my memory is being used on seemingly nothing

64 bit eats twice more ram then 32bit, you could start with uninstalling some dell bloatware you have preinstalled

Boot the pc and let it sit for a few mins.
How much ram is being used?

Windows keeps unused code in ram anticipating possible instant reuse.

To check if you are truly short of ram, start your normal activity.
Open task manager/ resource monitor and select memory tab.
Look at the hard fault column.. It lists hard page faults per second.
A hard fault happens when a needed virtual page is not in actual ram and must be fetched from the page file.
That is bad, particularly if your page file is a HDD.

A continuous rate of more than zero suggests you need more ram.

Normal condition. Every PC I own sits around the same while on desktop, whether it's win10 or win11. If the amount used concerns you add more, 8GB would be the bare minimum these days but for simple browsing and office tasks it will suffice.
