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?
Here is a nice video that gives you an easy to grasp intuition about durations of different operations and access of components of a computer (Cache vs RAM vs SSD vs HDD etc.)
I find it illustrates well why a fester drive or even faster RAM (unless there is a different bottleneck) would give you a more noticable performance uplift than a different Kernel.
