Performance On Linux. Just How Far *Can* We Go?

Linux and performance in the same sentence makes for an interesting topic of discussion. Everyone knows there is a multitude of options available to us. In this article, I’m going to attempt to cover a few of them.

The first thing we need to work out is are we using a source based distribution (eg. Gentoo/Funtoo) or a Binary based distribution (eg. Fedora/Debian/Ubuntu). Each of these examples carry some variables that the other ones don’t. Source based distributions allow you to modify the compiler options to optimize the code at build time, whereas the binary based distributions don’t allow us to do this (unless I’m proven wrong).

Starting with the source based distributions, we can find the best CFLAGS to run by a quick trip to the following link https://wiki.gentoo.org/wiki/CFLAGS.
