I installed Devuan 3 on my old Toshiba NB200 that for the last 6 months, and for some reason I can't figure out, was way slower than even its specs would imply, no matter what OS I tried (antiX, Mint XFCE, NetBSD, FreeBSD, WinXP, Win7 etc.), what RAM it had, what HDD or even SSD it had! I even serviced that thing, which turned out to be a good idea, although largely ineffective in solving my problem. Well, somehow it ended up being quite snappy with that distro, even capable of web browsing, true to the word 'netbook' after all these years. In fact, I'm using it right now to post this. The keyboard on it is a pure joy.
I also installed Devuan on my overkill ME/2k P4 PC, mostly to have ME and 2000 (which are on separate HDDs) easily choosable via GRUB without having to press F11 to choose the boot device from the BIOS, but also to have a usable Linux environment to browse the web for patches to the games I play on that PC, using that very same PC without having to worry about vulnerabilities or incompatibilities with the modern web. It's surprisingly slower than my netbook. I also figured out how to load soundfonts and play MIDI files on the Audigy 2 card using the actual Emu10k2 chip, rather than a software synthesizer. That one was a bit challenging, but worth it 😉
If you're wondering, Devuan is basically good old Debian, except it doesn't have systemd, using the older SysVInit instead. I picked it because I thought it would be more lightweight than a mainstream distro due to the less 'bloat'. Turns out, it didn't really make a difference as far the P4 is concerned at least. I'm not changing the distro on my A100 anytime soon, either. I want to have all of my computers to run some form of Linux/Unix at some point, old or new. That should be fun on my Pentium MMX 😉
