What is TCMalloc?

TCMalloc (Thread-Caching Malloc) is a high-performance memory allocator developed by Google. It is optimized for multithreaded applications and reduces contention between threads when allocating and freeing memory.

Main features of TCMalloc:

• Uses thread-local caching of memory to minimize locking.
• Fast allocation and deallocation of memory.
• Improved performance compared to standard malloc in a multithreaded environment.

It is used in systems where high speed and scalability of memory operations are important.
