Quoting Matthias Andree <mandree@freebsd.org>: >There is some analogy - not sure if we can learn something from it.

It is a delicate matter there also, and gladly we have plugable modules to do the job. (On my site only 'vegas' with specific parameters does give satisfying results - but then it does). >What I currently fail to understand is why we have not gone to improving >SCHED_ULE yet. This seems to be the first time I've paid attention to >some details. Have I missed similar discussion in the past? Or have >they stalled soonish? Indeed I don't remember these discussion going into the technical details inside the scheduler. Maybe nobody (including me) was eloquent enough to push it there?
