Load balancing evenly distributes the load generated by Vusers among the requested load generators, ensuring an accurate load test.
When a Windows load generator's CPU usage becomes overloaded, Controller receives a message and stops loading Vusers on the overloaded load generator, and automatically distributes them among the other load generators taking part in the scenario. Only where there are no other available load generators in the scenario does Controller stop loading Vusers.
You can monitor the status of a machine's CPU usage using the icons in the Load Generators dialog box (see Load Generators dialog box). When the CPU usage of a load generator becomes problematic, the icon to the left of the load generator name contains a yellow bar. When the machine becomes overloaded, the icon contains a red bar.
Note: Load balancing is available only in manual scenarios in the percentage mode, and in goal-oriented scenarios.
