Red Hat Enterprise Linux 6 (RHEL6.1) vs Debian 6 - A performance comparison

Today a plethora of Linux distributions and spins are available for desktop usage, each of them with some peculiar features that enable it to gain a sometime big, other times small, user base.

However in the server landscape things are considerably more rigid: the vast majority of the installed base is shared by 3 or 4 “big names”. Two of these “big names” surely are Red Hat and Debian, two Linux distributions with quite different targets – and background philosophy. These differences are often so great that you have little doubt in the choice between the two; however, sometime you are in a position where you simply want to pick the best-performing Linux distribution, regardless of other parameters as cost, management, ect.

So: what is the faster between RHEL 6.1 and Debian 6.0.2? Hopefully this article will respond to this question. Nevertheless, you surely know that comparing two full-blow operating systems is not an easy task: you must account not only for different usage patterns, but for different default settings. So, while I hope to give you some interesting informations, remember that I don't want to elect the always-faster, non-plus-ultra, uber-superior Linux distribution on the planet.

With this thing in mind, we can proceed to examining the two software configurations used to run the benchmarks.

Although I do like your comparison between the two systems I don't think there is a real use case for using an off the shelf installation and being the fastest distribution. It will be much more efficient to look at tuning the distribution you are familiar with to give the best performance.

Hi David,
I can see your point.

However, I saw many, many Linux hosts/services configured with default settings. In this case, the distribution-sp ecific default configuration will be a relevant part of the equation.

And other articles will cover application-spe cific tuning ;)
