===== v1.2.3 =====
Theses are benchmarks made with :
  * RSBAC version 1.2.3.
  * Linux Kernel Gentoo Hardened RSBAC 2.6.7-r10
  * GCC 3.3.4
  * PaX is enabled everywhere as in Gentoo [[http://hardened.gentoo.org/rsbac/quickstart.xml|Quickstart]]
  * Gentoo 2004.3 in Single User Mode
  * A Pentium-M 733 ULW (Dohan) @ 1.1Ghz, speedstep Off
\\ 
\\ 
//All tests were run 3 times and the average calculated in second.
We are compiling a vanilla 2.6.9 kernel from kernel.org//

\\ 
\\ 

Four kernels have been tested:
  * Vanilla Hardened, means rsbac-dev-sources, features Gentoo 2.6.7 patchset and Hardened patchset and RSBAC off. (No framework)
  * RC + Auth
  * All RSBAC Options On
  * Default Gentoo RSBAC kernel as specified in the Gentoo [[http://hardened.gentoo.org/rsbac/quickstart.xml|Quickstart]]

Real represents the real time spent, in seconds
User represents the total of CPU-seconds in user mode
Sys represents the total of CPU-seconds in kernel mode
Lower is better.

^		^real	^user	^sys   ^
^	Vanilla	| 656	| 619	| 26 |
^	RC+Auth	| 661	| 619	| 34 |
^	Gentoo	| 664	| 620	| 44 |
^	All On	| 679	| 623	| 58 |

All theses values are percentages of performance decrease, based on Vanilla = 100 percent. Lower is better.

As you can see, only the kernel mode time increase significantly in RSBAC 1.2.3, but there are only very few actions done in this mode so it doesn't really affect the real time very much.

To sum it up, we have a 1.2% difference of real time taken with a production kernel setup (Gentoo config), only 0.7% on a RC+Auth only enabled kernel, and a bigger 3.5% with every single option on.
