A Memory Pool is a method used in computer programming to manage memory allocation efficiently. Instead of requesting memory from the operating system each time a program needs it, a memory pool allocates a large block of memory at once. This reduces the overhead of frequent memory requests and can improve performance, especially in applications that require many small memory allocations. Memory pools are often used in systems with real-time requirements, such as video games or embedded systems. By pre-allocating memory, developers can minimize delays caused by dynamic memory allocation, leading to smoother performance and more predictable behavior in applications like game engines or real-time operating systems.
