Jemalloc

Definitions

1. A general-purpose memory allocator designed to reduce fragmentation and scale well under multithreaded workloads. It is widely used in high-performance systems and databases because its arena-based design and size classes can improve allocation behavior compared with default libc malloc implementations.

   In plain English: It is a fast memory-management library that helps large programs use RAM more efficiently.

   Example: "Switching the cache process to jemalloc flattened memory growth and cut allocator contention under load."
