| |
Hi,
I am currently looking for volunteers who want to evaluate the performance of the scheduler bigpatch on LARGE multi- user machines.
The scheduler bigpatch contains a number of items -- all of which have proven to work stable under the most obscene loads -- that improve the Linux scheduler with respect to interactive respons, realtime response and overhead.
The particular feature that might contain a few performance thingies is the improvement of interactive response. The (often large) improvement is achieved through load-independant 'recharging' of the priorities of processes that have slept for a period.
I have a slight suspicion that on machines where most of the load is generated by interactive programs (100+ people reading mail at the same time) the load-independantness might actually degrade performance a bit compared to what it could have been with an optimal scheduler.
Since it's all about _perceived_ performance testers don't need to do any complicated measurements at all, just tell me your impressions...
The scheduler bigpatch is available for kernel versions 2.1.125 to 2.1.131. If you have always been afraid of development kernels, this is the time to make the switch to "pre-2.2" 2.1.131, which is as stable as 2.0 will ever be...
You don't have to be afraid about the stability of my patch either -- it's been tested (read: severely abused and stressed to infinity) on quite a lot of systems for the last two months now.
You can get the patch from: http://www.phys.uu.nl/~riel/patches/
thanks,
