A new whitepaper from VMware shows the performance on vSphere 5.
In this Whitepaper you'll see the compare results of vSphere 4.1 and vSphere 5 by running Exchange 2010 Mailbox server. A tool called Microsoft Exchange Load Generator 2010 was used to run those tests. LoadGen runs on a client system and simulates the messaging load against Exchange Server deployments. LoadGen measures user response times for each of the different types of operations that it runs against the Exchange Server systems. In this case, LoadGen was configured to simulate Outlook 2007 online clients using the LoadGen very heavy–user profile, with 150 messages sent and received per day per user. Each mailbox user was initialized with 100MB data in the mailbox before starting the tests.
The author of the ressource is Vincent Lin, who works as a performance engineer at VMware. In this role, his primary focus is to evaluate and help improve the performance of VMware products in better supporting key enterprise applications. Prior to coming to VMware, Vincent was a principal performance engineer at Oracle. He received a Master of Science degree from the University of West Florida.
This paper examines the performance implications of scaling up an Exchange Server 2010 mailbox server virtual machine in vSphere 5 in comparison to vSphere 4.1 (increasing the number of virtual CPUs in the virtual machine) and scaling out with multiple Exchange Server 2010 virtual machines (increasing the number of virtual machines to the host). This paper includes data showing significant performance improvements of vMotion and Storage vMotion in vSphere 5.
