Performance isolation and adaption in the Vortex Kernel

Vortex is a new multiprocessor operating system kernel intended for emerging Internet service applications. The architecture is based on SEDA's staged computational model. Vortex provides mechanisms for performance isolation and dynamic adaptation. Performance results validate that the resource control mechanisms of Vortex are effective, and that Vortex significantly outperforms Linux on single-threaded web servers. The paper concludes with a description of how we plan to support a highly scalable event stream filtering service.
