memory allocator performance tester

Memory Allocator Benchmark

• You can measure the performance of variety memory allocators.

• Windows LFH(malloc/free,new/delete)

• Microsoft Concurrency runtime - https://msdn.microsoft.com/en-us/library/ff829272.aspx

• Intel TBB malloc - https://www.threadingbuildingblocks.org/

• Google tcmalloc - https://github.com/gperftools/gperftools

• You can test your custom or another memory allocator easily.

• High-Performance multithreading applications( like a server application ) needs high-performance memory allocator.

Usage

• open MemoryAllocatorBenchmark.sln
• build with x64 platform and Release.
• execute just batch file for benchmark.

$ bin\MemoryAllocatorBenchmark.bat

Benchmark

• Because of memory allocators may has a memory pool, it is so different between first allocations and second allocations.

• it tests to execute processes several times.

• it tests several times allocations to measure the differences between first allocation and second allocation.

• Defaults

• Variable block size : 8bytes ~ 32K bytes

• Mulith-thread : 4 threads

• count of allocations/deallocations : 10000

• method of allocation : run sequentially, run concurrently

Environment

• Windows
• C++
• Visual Studio 2015

Extras

• it uses high_resolution_clock of C++11 to measure the performance.

Enhancement Requests

• support more memory allocators
• support more Operating Systems
• support more IDEs
