TCMalloc is Google's fast, multi-threaded memory allocator implementing C's malloc() and C++'s operator new. It is a drop-in replacement allocator designed for high performance in multithreaded C and C++ applications.
Use cases
- replace glibc malloc with a faster allocator in a C++ server
- reduce lock contention in multithreaded allocation-heavy workloads
- profile and tune memory allocation behavior in production services
- link a custom allocator into an existing C or C++ codebase
When to choose
- your application is multithreaded and allocation performance matters
- you need a battle-tested allocator used at Google scale
- you want per-thread caching to reduce allocator contention
When to avoid
- your workload is single-threaded with minimal allocation overhead
- you need a platform not listed in TCMalloc's supported platforms guide
- you require a simple allocator with minimal build complexity
