Performance Evaluation of AMD RVI Hardware Assist
AMD recently introduced its second generation of hardware support for virtualization, incorporating MMU virtualization called Rapid Virtualization Indexing (RVI). Hardware support for MMU virtualization can improve performance, particularly for MMU-intensive workloads.
VMware ESX 3.5 leverages this RVI support in AMD processors. This paper compares the performance with and without RVI of a number of industry-standard benchmarks and microbenchmarks running in VMware ESX 3.5, Update 2 on AMD Opteron 8384 ("Shanghai") processors.
