Excerpt
Excerpt Many general-purpose memory allocators implemented for C and
C++ provide good runtime and low fragmentation for a wide range of applications. However, using specialized memory allocators that take advantage of application-specific behavior can dramatically improve application performance. Handcoded custom allocators are widely used: three of the twelve integer benchmarks included in SPEC2000 (parser, gcc, and vpr) and several server applications, including the Apache web server and Microsoft’s SQL Server, use one or more custom allocators.
Custom allocators can take advantage of certain allocation patterns with extremely low-cost operations. For example, a programmer can use a region allocator to allocate a number of small objects with a known lifetime and then free them all at once. |

Claims
3
The method as claimed in Claim 2, wherein said maintained information comprises information representing how one or more pools are organized, said one or more pools being organized according to a criteria selected from the following: a process, a user, a security context, a processor, an applications node's status as being a Non-Uniform Memory Access (NUMA) node, or, a memory zone where fixed size freed memory units are made available.
Relevance
The claim describes a policy based selection criteria for memory pools. This prior art teaches us that such customised allocators already existed.
