More Info: Dual-core Latency Advantage

Faster cycle times mean higher bandwidth controllers, a desirable trait because it leads to improved performance and throughput. 10-30 microseconds of jitter is significant when cycle times of 50 to 200 microseconds are required. If jitter is a significant percentage of the cycle time it adversely affects the quality and stability of the control algorithm, which are directly related to the accuracy of the cycle time. Variations in the cycle time degrades the stability margin of a closed-loop control system, especially naturally unstable systems like position-feedback motion control loops.
