In most cases, the back-end CPU utilization percentage is a single percentage number, representing the highest single thread utilization, with the other threads being under control. In a few cases, the back-end CPU utilization percentage has multiple numbers (see Table 17), which represents the order of thread execution—the top two (or four in the case of eight Execute Thread tests) are Local Query Handler (LQH) threads, which execute a major part of the work.
