The Slab Allocator An ObjectCaching Kernel Memory Allo: Transcript

4 kernel memory allocator This allocator is based on a set of objectcaching primitives that reduce the cost of allocating complex objects by retaining their state between uses These same primitives prove equally effective for manag ing stateless memo.
