[gentoo-user] Linux Magazine tests Gentoo performance

I suppose this is interesting to most Gentoo users. Linux Magazine
performed a detailed benchmark of Gentoo, comparing it to Ubuntu 9.04:

The conclusion (Gentoo clearly outperforms Ubuntu) is no surprise, but
it's still an interesting read.

Before you ask: the article *does* mention that Gentoo's point is not
"faster optimization" (aka "for ricers") but it's just a side effect of
Gentoo's architecture.

Btw, I think this is a very nice example of why per-package CFLAGS would
have been very useful. Some application largely benefit from -Os, others
from -O2.

If you're willing to put in a bit of effort, I believe you can set up a
per-package environment (including custom CFLAGS) in a number of ways.
The one that seems to be most popular is described here:
