I have the following kernels installed:

  • linux-zen (Zen)
  • linux-rt (RealTime)
  • linux-hardened (Security Hardened)
  • linux-lts (Long Term Support)
  • linux-tr-lts (Realtime LTS)

When I boot up, I try the different kernels from time to time just to see if anything interesting happens. It never does.

My question: How do I actually physically notice the difference between these kernels? If I use RT, does Firefox spawn quicker (in my testing, no, not really)?

What are some use cases when I can really see the difference in these kernels?

    Realtime is not about being fast, it’s about time guarantees. It helps with or is required for workloads that require realtime, which I think includes audio production, but might also be helpful for things like controllers etc. where you need to make sure incoming data is processed in a guaranteed time or else fail. Browsing the web isn’t part of these, so an RT kernel will most likely be a hindrance.

      Ok this discussion reminds me of a gripe: Is there a Linux distribution or kernel that prioritizes the UI over everything else, including an OOM situation?

      I’ve never had (modern) Windows kernel panic on me, or completely slow to the point I can’t get Ctrl+Alt+Del registered.

      Let me know if I’m just using Linux stupidly though…
