What is background noise in performance testing?

Background Noise: When designing a load to test the performance of a Web site or application, consider what additional activities need to be added to a test environment to accurately reflect the performance degradation caused by “background noise.”

Background noise is created by other applications running that will also be running on the production servers once the application under test moves into production, and other network traffic that will consume network bandwidth and possibly increase the collision rate of the data packets being transmitted over the LAN and/or WAN.
