Can anyone tell me why I see swap usage with 10+GB of free RAM available?
If you(or your distro) use zram then the zram usage may also count as swap in resource monitors. For me this was the case when i saw swap usage where it is clearly not needed to swap. You can check it with
swaponcommands.Other reason is that more frequently accesed files may be cached to ram and less important stuff gets swapped. But if you notice swap being used while total ram usage including cached is much lower than total, then its probably zram(and it does write to disk so dont worry about that)
Saving ram to swap can be done with minimal impact. Helpful when you run out of memory and that 2gb app idling can be dumped right away instead of waiting for it to be copied to swap.
but that's not what's happening. processes do actually get removed from RAM, and when they are needed they are very slow until they are loaded back. the system thinks it's more valuable to have that memory be filesystem cache
If true then Linux is a decade behind windows and macOS.
tbh windows was doing this very aggressively on my system, it was swapping like a mad man right when memory usage reached 50%
Doubt. It might be copying to swap, but not reading from it.
Swappiness set to over 9000!
