mimalloc is a compact general purpose allocator with excellent performance.

TCMalloc

TCMalloc is Google's customized implementation of C's `malloc()` and C++'s `operator new` for memory allocation within C and C++ code. It provides a high-performance alternative to standard memory allocators, optimized for multi-threaded applications where allocation speed and scalability are critical. ## Key Features - **Fast Allocation** — Optimized for speed with efficient memory management algorithms - **Multi-threaded Performance** — Designed to scale well in concurrent environments - **Customizable Configuration** — Tunable parameters for different workload requirements - **Comprehensive API** — Full support for C and C++ memory allocation interfaces - **Platform Support** — Available across multiple operating systems and architectures ## Philosophy TCMalloc prioritizes performance and scalability in multi-threaded environments while maintaining compatibility with standard memory allocation interfaces, making it suitable for production systems with demanding memory allocation patterns.
