From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A noticeable difference in kernels? (lemmy.ml)

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?

I don't think there will be a noticeable difference. Real Time kernel is intended for things like microcontrollers I believe.

Realtime is important on fully fledged workstations where timing is very important. Which is the case for a lot of professional audio workloads. Linux is now another option for people in that space.

Not sure Linux can run on microcontrollers. Those tend to not be so powerful and run simple OSs if they have any OS at all. Though this might help the embedded world a bit increasing the number of things you can do with things that have full system on chips (like the Raspberry pi).

So it's more for dealing with hardware interruptions quickly, and likely will not help with gaming?
