ESX Performance Report
Phil Windley’s “Technometria” has recently posted a “VMware ESX Performance Report”
Some of their conclusions:
-
Single CPU virtual machines scale better than virtual machines using Virtual SMP.
-
Hyper-Threading increases throughput if there are a large number of virtual CPUs, but makes no difference if the number of virtual CPUs is less than or equal to the number of physical CPUs.
-
Do not allocate excessive resources to virtual machines. Additional resources may hurt performance.
