An engineering team develops a real-time monitoring system to process a continuous, unending stream of user activity events. During testing, they observe that the system processes the first few thousand events quickly. However, as the system continues to run for several hours, the time it takes to process each new, individual event steadily increases, leading to significant delays. Which of the following design principles is the most likely cause of this performance degradation?
