I’ve never understood why GNU/Linux actually needs swap. Okay, I created a 4G partition for it, having 32G of RAM. I never used all that RAM, but even so, stuff regularly ends up in swap. Why does the OS waste write cycles on my SSD if it doesn’t have to?
However, if I artificially fill up all 32G of RAM, the system almost completely freezes faster than switching to using swap as a “lifeline”. And it only comes back to life when OOM Killer finally remembers its existence and kills some f__ing important process.
