As reflected by the robust capabilities of industry-standard load testing tools such as HP LoadRunner, the proper setup and execution of a load test is a complex undertaking. Significant effort goes into each load testing project. Organizations that are disciplined enough to properly implement performance testing into their application development lifecycle have gained significant business benefits from finding issues and properly sizing capacity prior to application roll-out. Increasingly, many pre-deployment testing labs have found that it is critical to incorporate the impact of WAN on application load testing. This white paper describes the importance of assessing network impact on application performance and the value that is obtained by integrating WAN emulation into load testing.
