[SOLVED]Differences between kernels ?

I hope this is the right place. It said "question concerns".

I'm wondering if someone who has tested it can tell me the performance difference between zen and linux-stable/linux-realtime?

For example, when I run windows in vbox, + (there are 4 workspaces, music playing in the background, about 20 tabs open, video playing, vscode open) I see that RAM is 50% and then it goes up to 60. How much RAM do these processes use in zen ? Or if a percentage can be given in general ?

I don't know if it is up to date and real or if it can be reflected in every field, but I found this comparison on the internet: https://www.phoronix.com/review/arch-li … els-2023/7

The LTS kernel was always going to fare badly because those tests were on 7th generation Ryzen hardwarwe, which was very new when the LTS version was released.

I've never noticed any difference between the kernel versions.

Re: [SOLVED]Differences between kernels ?

I guess the only difference is the purpose then. They say some programs don't work on Hardened, it's called security.

I don't understand the support in LTS. "The best Linux kernel possible for everyday systems." says the wiki for Zen, is it any different from Vanilla ? And what about Realtime ?

Re: [SOLVED]Differences between kernels ?

The benefit of the LTS kernel is that it doesn't get a steady stream of new regressions features, and so is more reliable, at least in theory.

The RealTime kernel is for special cases such as audio production where absolute timing is essential. Having said that I have heard professional sound engineers say that the vanilla kernel offers sufficiently low latency for most purposes these days.
