The v2 Rotary Interactivity Favor Scheduler
Version 2 of the Rotary Interactivity Favor Scheduler (RIFS) was published on Friday. The RIFS scheduler for the Linux kernel is designed for driving a low-latency Linux desktop.
The Rotary Interactivity Favor Scheduler places the priority of interactive tasks prior to that of CPU bound tasks. All interactive tasks get first stabs to allow for low-latency interaction. The design of RIFS is based upon the multiple feedback queue algorithm.
Details -- along with a patch for RIFSv2 -- can be found on the kernel mailing list.
Benchmarks provided by Mou Chen, the author of the Rotary Interactivity Favor Scheduler, on the mailing list claims even better performance than the Brain Fuck Scheduler.
