NixOS resuscitated a 2012 Macbook Air. This thing flies! I was NOT expecting that at all (lemmy.ml)

As per title, I am mind-blown by the speed and stability of NixOS on this "relic" in IT terms... On this machine i tested:

Distro	Performance
Fedora	MEGA slow
Ubuntu	OKish
LDME	Fast
Debian	Fast
NixOS	VERY Fast

And the best thing is that I can bring this config with me on any computer! Oh boy, I think i have fallen in love with NixOS

Generally yes.

Here is two examples from my recent experience:

Run custom realtime software on rt and non-rt kernel: Huge difference when I look at milliseconds and latency.
I ran Minecraft recently on the standard and rt kernel, with realtime it performs much better (no dGPU)

I will look into nixOS definitely. Last time I checked must have been 2018 hehe

Right if you have applications with rt constraints, you'll obviously need a rt-capable OS but that's more a matter of it being available as a feature, rather than being performant enough.
