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?
My mind was on Unix systems with real time kernels from a time when Windows were but openings in the wall or roof of buildings or vehicles, fitted with glass in a frame to admit light or air and allow people to see out. And later Linux.
