Belady's Anomaly

Belady's Anomaly refers to a counterintuitive situation in computer memory management. Typically, as you add more memory space, you expect a program to run faster and use fewer resources. However, Belady's Anomaly shows that, in some cases, increasing the amount of memory can actually lead to more page faults—instances when the system needs to retrieve data from the slower disk instead of the faster memory. This odd behavior occurs with certain algorithms for managing memory, highlighting that simply adding resources doesn't always guarantee improved performance.
