How long would it take to be considered an inactive memory page? Does OOM conditions immediately trigger compression, or would the process die first?

[โ€“] tdawg@lemmy.world 1 points 1 day ago

So I'm not an expert but my understanding is the flow is roughly:

  1. Available memory gets low
  2. Compress based on LRU rules
  3. Use swap
  4. OOM

So it's more meant to be preventative afaik
