Theses are benchmarks made with :
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:
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.
real_p | user_p | sys_p | |
---|---|---|---|
Vanilla | 100 | 100 | 100 |
RC+Auth | 100,7 | 100 | 130,7 |
Gentoo | 101,2 | 100,1 | 169,23 |
All On | 103,5 | 100,6 | 223,07 |
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.
