Many real-time operating systems use memory pools, such as the Transaction Processing Facility. The maximum size of the cache is static and is defined at compilation time (CONFIG_RTE_MEMPOOL_CACHE_MAX_SIZE). Fig. 5.3 shows a cache in operation.

GNU MemPool It is a block allocator library that uses a single fixed size memory pool to allocate variable sized memory blocks, and exports functions similar to malloc, realloc and free. It is intended to either simulate low memory targets on GNU/Linux and other systems, or to completely replace the system memory management. The size of the mempool is constantly fluctuating as transactions are confirmed and new transactions are placed in the mempool. In case your transaction gets stuck, then you can use a transaction accelerator or transaction pusher service to get a solution. A more efficient solution is preallocating a number of memory blocks with the same size called the memory pool. Here we can see some statistics related to the state of our local mempool which reports to have a size of 0, meaning that it is empty.
