/Documentation/scheduler/
Dsched-nice-design.rst6 nice-levels implementation in the new Linux scheduler.
8 Nice levels were always pretty weak under Linux and people continuously
16 In the O(1) scheduler (in 2003) we changed negative nice levels to be
58 To sum it up: we always wanted to make nice levels more consistent, but
83 nice levels were not 'punchy enough', so lots of people had to resort to
90 To address the first complaint (of nice levels being not "punchy"
92 (and granularity was made a separate concept from nice levels) and thus
98 To address the second complaint (of nice levels not being consistent),
100 tasks, regardless of their absolute nice levels. So on the new
104 levels were changed to be "multiplicative" (or exponential) - that way
