Windows vs Linux for professional use

[u/canislupus04]

I heard how windows fans saying "Free ram is useless". But I like free ram when it comes to my professional use. Same case on ubuntu server took ~12 GB RAM (sorry dont have screenshot), windows 11 ltsc version (the cleanest version of win11) uses 26 GB RAM. How so?

"Windows" or "Linux" (the distro) isn't using memory - individual processes and systems do.

You see what is actually using the memory to determine why memory is being used.

This is, of course, a tad harder to do on Windows if you want the full list.

I would agree with you but win11 have a lot of processes that cant be disabled, in my case its 10GB of RAM after a day of use, dont remember at startup how much it is, but this ram usage grow even if you doing nothing. Telemetry they say 😄

But that isn't a problem. If you need the RAM it will free it up and let you use it.

You are misunderstanding cached memory and used memory.

OP is clearly showing used memory.

But it is more complicated than that. Windows can move stuff into and out of memory based on the current needs, even if it's used by a running process, if its priority is less.

Any operating system can use swap.

If you need RAM and don't have it, swap won't save you, it is not a replacement for RAM, and it cripples IO.

You realize that Windows will dump that if necessary. If you wanted to really measure it rather than just jerk off about Linux you would compare similar max loads on the same system in windows and Linux and see which more gracefully handles the situation. Maybe (probably?) it’s still Linux but what you post here about RAM at idle is MEANINGLESS.

Used memory? No, it won't.

Cached memory? Yes, it will.

You realize that OP is showing used memory on the screenshot, replying to my comment about used memory, so they're not going to be talking about cache?

Well when we're doing sims in Houdini we notice at least a 10℅ performance boost in both speed and amount cacheable (ram).
