Hi,

I know that constant switching time of the Linux scheduler was a big achievement. I was just asking myself the question what would be the implication of a non-constant switching time. The only obvious reason I can think of is real-time systems where we have to meet deadlines. There it is obviously no ideal if the switching time is "random". Are there any other good reasons that favour constant switching times?

Many thanks, Rob
