TCMalloc
Google's fast, multi-threaded malloc implementation for C and C++ memory allocation.
What is TCMalloc?
TCMalloc is Google's fast, multi-threaded malloc implementation for C and C++ memory allocation. It serves as a high-performance alternative to standard memory allocators, optimized for applications where allocation speed and scalability across multiple threads are critical. The library provides customized implementations of C's `malloc()` and C++'s `operator new` used within Google's C and C++ codebases.
C and C++ developers building high-performance, multi-threaded applications where memory allocation performance is a bottleneck. System programmers and performance engineers working on scalable server applications, databases, or real-time systems.
Developers choose TCMalloc for its superior performance in multi-threaded environments compared to standard allocators, with Google's production-proven implementation and extensive tuning options. It offers better scalability and lower latency for memory-intensive applications while maintaining API compatibility.
