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

Why do you feel nix is faster than the other builds? Something related to graphics drivers?
I guess there is just less bloat running in NixOS. But then again, the difference between Debian and NixOS is very subtle. Debian/LMDE run great on that hardware
