I'd like a more systematic way for prioritizing my tasks with nice(1).
Obviously 0 is "normal", 19 is "lowest priority" and -19 is "highest priority", but what about all the other numbers?
If I have a job that is non-interactive (I'll go get coffee while it runs), I'd like to lower the priority a bit, but to which number? Should it be 1 or 2 or 10 or what?
Are there any "well-known" things that each priority number is used for?
The same questions apply to ionice.
