RIFS-ES Linux Kernel Scheduler Released

Another idea regarding your statistic:
It is not meant to show the latency of the overall system, but the performance of a single function ordering the loads compared?
(the logN efficiency you mentioned erlier)

It shows the latency of 'sleep 10'

This is funny!
Is this a quantum machine running faster on high loads?

Yes, this is very weird.
I don't think this is possible.
Why the graph look like this?

Hi

Here is a newer benchmark around latt -c255 sleep 10 between these 3 cpu scheduler.
http://code.google.com/p/rifs-schedu...Result-003.PNG

RIFS-ES-Low-Spec has been posted, if you want a link please click the follow site.
http://rifs-scheduler.googlecode.com...ec-kernel3.4.x

After using it if you think it is useful please invite the others to use it. :)
Thanks

Chen

EDIT 2

All right I am going to make a conclusion for the benchmark
Although BFS get the worst average latency but it also get the best max_latency value.:cool:

Looks very weird.
The latency jumps up and down unpredictably instead of scaling smoothly.

Even it jumps up and down it is still lower than the other 2 scheduler.
During the test I will move the mouse(I just move the mouse and I don't click anything).
With BFS the mouse stalls.
With CFS or RIFS-ES-Low-Spec the mouse is very smooth.

With average latency RIFS wins, with maximum latency BFS wins.

I just run a linux-3.4.4rc using the additional patch
RIFS.ES-v1-low-spec-kernel3.4.x

No issues with audio as was before!
Very smooth experience with high load
compile + flash + video
all at the same time!

Thank you very mush Chen!

The BFS alternative will have issues with the newest linux-3.4.4
regarding a rpc patch as I pointed to at Kon Colivas blog.

Thanks for trying. :)
If the mainline can make CFS smooth then RIFS will stop publishing.
The existance of RIFS is to make the kernel smooth.:)
If you want you can invite the other to us it, or you can hack the scheduler and post your hacking.:)

We have to let the maintainer to know that they should improve the desktop user experience now.:cool:

I have made an decision that I will still continue maintaining and developing it even after the mainline has improved the interactive :cool:

I am publishing my esperience here:
http://siduction.org/index.php?name=...93b39deb#21450

Siduction is an effective an little community around Debian unstable. Towo, the kernel guy there, had applied BFS patches for Linux-3.2 back then. But you dont have to use it to discuss in the forums. My main distribution yet is Gentoo, which is not only a "rollin' release" but a rolling MYrelease.
