[gentoo-user] Linux Magazine tests Gentoo performance

[Nikos Chantziaras]

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

   http://www.linux-mag.com/id/7574/1

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:

I am using a much simpler (for me thing). Just create for every package
you like to change things a kind of pseudo make.conf in

/etc/portage/env/CAT/

There you can change everything on package basis, not only FLAGS, but
also FEATURES etc.
