Linux: Replacing atime With relatime
,----[ Quote ]
| Ingo Molnar stressed the significance of fixing this performance issue, "I
| cannot over-emphasize how much of a deal it is in practice. Atime updates are
| by far the biggest IO performance deficiency that Linux has today. Getting
| rid of atime updates would give us more everyday Linux performance than all
| the pagecache speedups of the past 10 years, _combined_." He submitted some
| patches to improve relatime...

| Finally, my personal opinion about the new scheduler (still in heavy
| development) and 3D display performance. Well, one thing's for sure, desktop
| (compiz) is snappier. Simple tests of cube rotation while the kernel is
| compiling (on both cores) show that CFS is much better than the old
| scheduler, cube rotation is much smoother than before.

| 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

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.
