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

Synthetic benchmarks – CoreMark, Stream, Membench

First of all, I will focus on some synthetic benchmark results. The first benchmark is CoreMark, which measure the CPU performance. While it depend primarily on the target CPU and I don't expect its results to be greatly influenced by the distribution used, please remember that it was compiled against the distribution-specific libc stack and compiler.

Red Hat vs Debian - Coremark

As expected, we has vastly similar results, with Red Hat pulling slightly ahead.

How about memory bandwidth? Lets examine it by using STREAM...

... and Membench

Again we see very similar results, with Debian showing some very small advantages in certain tests.

So we can conclude that, as expected, the performance of the two Linux distributions in theoretical test is the same. This means that, from a CPU and memory standpoint, there are not obviously wrong things in (only) one of the two contenders.

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 ;)
