It's still getting there. I'd have to say that 10.04 was pretty much the fastest release I've ever used. System speed slowed down in releases after (even with Xubuntu), but 13.04 is somewhat closer to getting back. I tried out the Ubuntu 13.10 Alpha dev release for awhile and was pretty impressed with the speed. That was with Unity running so hoping that Xubuntu 13.10 will be equally speedy.

Because that's not the case, we have to do it with this technique.
It's also not logic-messing, but the processing of device-identifiers (part of eudev), so there's no real way around char-arrays, which are factually 8 bit unsigned-integer-arrays (effective enough) and in need to be returned.
In case you have a better idea, please let me know.

Originally posted by frign View PostOn the technical side, having a fast computer, of course, makes it hard to see which system's faster. My current computer is a quad-core i7 one, so I shouldn't see any difference, too.
For testing purposes, I set up Gentoo on a smaller system (fit-PC2 by CompuLab) and compared it to a fresh installation of Debian (Xfce). Especially using the Desktop Environment, you could notice some differences.
Humans are actually quite sensitive when it comes to little time-delays.
Debian ran just fine and I don't have any reason to complain. But using Gentoo on the other hand, it was noticeably faster. That was my personal experience and I might just fall for the placebo-effect, but everyone's free to do benchmarks.
If you search for benchmarks on the net, you normally find ones comparing different optimization-levels (which is BS). Honestly, no one really did a comparison between Gentoo and Debian for example (Correct me if I'm wrong).

Benchmarks are needed
Originally posted by juanrga View PostI don't know any modern comparison with a binary distro. Some forums posters in the internet report about a 10% speed advantage, but fail to give any detail of what exactly compared and how. I have also seen the -Os/O2/O3 comparisons, but nothing about USE-flags
I don't think there is an _overall_ 10% speed advantage, but there's definitely even more in some areas.

Good idea!
Originally posted by mrugiero View PostThe thing about comparing use-flags is that, first, there are too many variants, and second, it, by definition, means there is no feature parity when doing the comparison. Benchmarks are only extrapolated when there is feature parity. The point in use-flags is not loading things you don't use, and this is inherently a custom setting for a custom user, and thus not extrapolated. The closest you can get to actually make a valid comparison is stating you will always compare minimal features for a given package with default in another distro, with the same optimization flags (so to compare only the overhead introduced by features).
Going minimal may be the best choice.

If it is possible to benchmarks three different kernels, or ten different OSs, or six different CPUs, why couldn't be benchmarked five different use-flags in the same system, just to see what happens? They would be useful to get an idea.
