the bandwidth period) in the presence of idle cycles ?
I think we need to treat guarantees as first-class goals, not something derived from limits (in fact I think guarantees are more useful as they can be used to provide SLAs).
I agree that guarantees are important, but I am not sure about
1. specifying both limits and guarantees for groups and
2. not deriving guarantees from limits.
Guarantees are met by some form of throttling or limiting and hence I think
limiting should drive the guarantees
