Performance Evaluation of Intel EPT Hardware Assist
Mar 30, 2009
Intel® recently introduced its second generation of hardware support for virtualization incorporating MMU virtualization called Extended Page Tables (EPT). Hardware support for MMU virtualization can improve performance, particularly for MMU-intensive workloads.
This paper compares performance with and without EPT on a number of industry-standard benchmarks and microbenchmarks running in an internal build of VMware ESX on Intel Xeon 5500-series ("Nehalem") processors.
