I left my old desktop running since May 7, and just noticed that it was very noisy. I managed to ssh into it and found that it had used the 16gig of memory and 16 gig of swap.
When I left it running, I had a bunch of firefox windows running and top showed various “Web Content” processes consuming 15-17% of memory. Once I killed these the fan stopped, but I was left with the highest memory usage.
xfwm4 using 13.5% of memory and 2.1g in the RES column on top.

Whereas my new desktop has much more normal usage
if you leave content open, it’s running & won’t release what ever it’s using back to the system. xfwm4 is the window manager, it’s going to be involved with what ever is running & if the process doesn’t close or is constantly changing(web content) of course the memory is going to climb.
I have not seen it climb like that before. It has stayed high after the other high memory items were closed.
some content is cached, for speed purposes, if it’s a app you use regularly it might hold on to it longer.
are you experiencing slow downs / lock ups?
