mimalloc: A new, high-performance, scalable memory allocator for the modern era

mimalloc is a new, high-performance memory allocator designed as a drop-in replacement for standard malloc/free. This open-source tool offers bounded allocation times, low fragmentation, and minimal contention by using atomic operations, making it an attractive option for optimizing C/C++ applications that are memory-intensive. Its small codebase and clear design facilitate integration into existing projects.
