Why to use memory pool and how to implement it - CodeProject

WebMemory Pool is an optimization technique which is frequently used in all major Software Systems. The advantages of Memory Pool are: Allocating a single large memory takes significantly less time than multiple small chunks of memory (amounting to the same value). WebPool allocation is a memory allocation scheme that is very fast, but limited in its usage. For more information on pool allocation (also called "simple segregated storage"), see the concepts document. Why should I use Pool? Using Pools gives you more control over how memory is used in your program.

Web31 mei 2024 · Memory pools are used to implement custom allocators. One commonly used is a linear allocator. It only keeps a pointer seperating allocated/free memory. Allocating with it is just a matter of incrementing the pointer by the N bytes requested, and returning it's previous value. Memory pools, also called fixed-size blocks allocation, is the use of pools for memory management that allows dynamic memory allocation comparable to malloc or C++'s operator new. As those implementations suffer from fragmentation because of variable block sizes, it is not recommendable to use them in a real time system due to performance. A more efficient solution is preallocating a number of memory blocks with the same size called the memory pool. The appli…
