Performance Brief for IBM WebSphere Application Server 7.0 with VMware ESX 4 on HP ProLiant DL380 G6 Servers
This document describes the results of testing completed jointly by VMware and HP to study performance of IBM WebSphere Application Server on VMware ESX 4 with HP ProLiant DL380 G6 servers. As seen in the tests, VMware ESX 4 performance is at most 11% less than the performance of a comparable physical server without virtualization. In some test cases, VMware ESX 4 outperformed the physical environment. Both virtual and physical environments provided incremental performance gains as the number of active CPUs was increased.
