| |
Hi all,
some results based on massing_intr.c by Satoru, can be found on http://people.redhat.com/mingo/cfs-scheduler/tools/massive_intr.c
Runned several times like: $ massing_intr 5 2 >> results-kernel-5.2 $ massing_intr 300 300 >> results-kernel-300.300
To calculate average and standard deviation:
$ original-awk -f awkscript results-file
awkscript file included. (for debian users: apt-get install original-awk)
Here's the data, values and facts:
kernel run as average stddev ====== ====== ======= ====== 2.6.22-rc4-ck1 5 2 34 0 2.6.22-rc4-ck1 5 2 22 0 2.6.22-rc4-ck1 5 2 24.6 0.219 2.6.22-rc4-ck1 5 2 31.4 0.219 2.6.22-rc4-ck1 5 2 40 0

* "run as" it's the parameters passed to the program massive_intr.
All the files and data can be found on http://www.debianpt.org/~elmig/pool/kernel/20070611/
Just one note, the first time this test was run: -cfs-v16 i got this values: 44, 23, 19, 16, 42; -2.6.21-debian: 29, 25, 22, 16, 32; -ck1: 37 37 37 37 37
The machine was a Sempron64 3.0 GHz.
I know that other people, who read lkml, also tested the same way, it would be nice if they also post their data.
