Systems Programming and Performance Tuning
Systems Programming and Performance Tuning Systems programming sits at the edge of software and hardware. It means building components that run close to the metal, like libraries, servers, drivers, or kernel modules. In practice, the work blends correctness with speed: memory layout, timing, and cooperation with the operating system all matter. Begin with measurement. A clear baseline helps you know if changes help. Track latency, throughput, CPU utilization, and memory use under realistic load. Simple tools like top, iostat, and vmstat give a quick view, while more focused profilers reveal where time goes. ...
