mimalloc (pronounced "me-malloc") is a free and open-source compact general-purpose memory allocator developed by Microsoft[2] with focus on performance characteristics. The library is about 11000 lines of code and works as a drop-in replacement for malloc of the C standard library[3] and requires no additional code changes.[4] mimalloc was initially developed for the run-time systems of the Lean and Koka languages. Notable design aspects include free list sharding, eager page reset, first-class heaps. It can co-exist with other memory allocators linked to the same program. mimalloc is available on Windows, Mac OS X, Linux and *BSD.[5] The source code is licensed under MIT License and available on GitHub.[6]
