For CPU it will be, "container will get _at least_ X ticks in Y seconds" For number of tasks it will be, "container will get _at least_ X active tasks at any point of time" and so on. And as Dave pointed, sum of guarantees of all containers _can not_ exceed the total amount of that resource available at the system level. > > Let's decide what kind of a guarantee we want. > >> be worked out as we make progress. > >> > >>> I agree with these requirements and lets move into this direction. > >>> But moving so far can't be done without accepting: > >>> 1. core functionality > >>> 2. accounting > >>> > >> Some of the core functionality might be a limiting factor for the > >> requirements. > >> Lets agree on the requirements, I think its a great step forward and then > >> build the core functionality with these requirements in mind. > >> > >>> Thanks, > >>> Kirill > >>> > > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
