How mmap Works: File-backed Memory Mapping, Coherence & Writeback Deep Dive
In this video, we dive into the world of memory-mapped files (mmap), a powerful mechanism used by operating systems to map file data directly into a process’s virtual memory. We'll explain how mmap allows applications to treat file I/O like ordinary memory access, and why this is critical for performance and low-latency systems. By the end ...

On Linux, malloc manages heap memory using brk() and mmap() under the hood. You can tune its behavior with environment variables (arenas, trim thresholds, mmap thresholds) and monitor usage with tools like /proc, valgrind, and heap profilers. Master malloc, master memory efficiency. #linux #computerscience #programming #software | Command & Code
