Inside the Linux 2.6 Completely Fair Scheduler
,----[ Quote ]
| The task scheduler is a key part of any
| operating system, and Linux continues to
| evolve and innovate in this area. In kernel
| 2.6.23, the Completely Fair Scheduler (CFS) was
| introduced. This scheduler, instead of relying
| on run queues, uses a red-black tree
| implementation for task management. Explore the
| ideas behind CFS, its implementation, and
| advantages over the prior O(1) scheduler.

BFS Scheduler Benchmarks
,----[ Quote ]
| While BFS lost with the Threaded I/O Tester disk benchmark, it won with the
| PostMark test profile. The BFS scheduler delivered just fewer than 5% more
| transactions per second than the Completely Fair Scheduler.
|
| Nine tests carried out on a single low-end system (we may carry out more tests
| on multiple systems if there is sufficient interest) is not enough to call one
| scheduler better than the other.

Con Kolivas returns with a new scheduler
,----[ Quote ]
| Con Kolivas, who worked on desktop interactivity issues in the past before
| storming off in 2007, has posted a new scheduler called BFS. "It was designed
| to be forward looking only, make the most of lower spec machines, and not
| scale to massive hardware. ie it is a desktop orientated scheduler, with
| extremely low latencies for excellent interactivity by design rather
| than 'calculated', with rigid fairness, nice priority distribution and
| extreme scalability within normal load levels."

CFS scheduler to appear in Linux kernel 2.6.23
,----[ Quote ]
| And also credit where credit's due, Con Kolivas was the first one to
| prove via RSDL/SD that 'fair scheduling' is possible and that it
| results in better desktop scheduling.

Linux: Revisiting Swap Prefetch
,----[ Quote ]
| Another thread discussed potentially merging the swap prefetch patch
| into the mainline Linux kernel. Con Kolivas started the thread saying
| "I fixed all bugs I could find and improved it as much as I could last
| kernel cycle. Put me and the users out of our misery and merge it now
| or delete it forever please."

Linux: Linus On CFS vs SD
,----[ Quote ]
| "People who think SD was 'perfect' were simply ignoring reality," Linus
| Torvalds began in a succinct explanation as to why he chose the CFS scheduler
| written by Ingo Molnar instead of the SD scheduler written by Con Kolivas.
