Comment on Why is my home server using so much RAM for cache + buffer?
brucethemoose@lemmy.world 6 days agoIt’s “free ram” until stuff actually goes in swap.
It depends on the scenario, of course. Maybe you have huge, totally idle processes, and active ones working from an HDD that need cache desperately, in which case this is good.
But my experience with Linux is that is waaay to aggressive with this, in most configs, and I get far better performance from configs that avoid swap until it absolutely has to be used.
Every use case is different and there is when you can customize it being Linux.
So good, sladapt your swappines and/or ditch swap completely or try zram, according to your needs. Standard use case works fine for most people tough.
