Pushing Performance Isolation Boundaries into Application with pBox

Modern applications are highly concurrent with a diverse mix of activities. One activity can adversely impact the performance of other activities in an application, leading to intra-application interference. Providing fine-grained performance isolation is desirable. Unfortunately, the extensive performance isolation solutions today focus on mitigating coarse-grained interference among multiple applications. They cannot well address intra-app interference, because such issues are typically not caused by contention on hardware resources.
