Performance Brief for IBM WebSphere Application Server 7.0 with VMware ESX 4 on HP ProLiant DL380 G6 Servers
Feb 4, 2010
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.
