Performance Engineering: A Practical Starting Map
Performance Engineering: A Practical Starting Map This is the first note in a performance-engineering sequence. It is not a summary of an SRE handbook, a cloud-observability guide, or a treatise on dashboard design. The goal is practical skill at the level of a single machine: understand why a program is slow, decide what to change, and verify that the change worked. The contexts that matter here are things like a chess engine, the microbenchmark problems on HFT University, a hot loop in the Linux kernel, or any single-node program where you own the source and the hardware. The operating system is the boundary we press against; the hardware is the ground truth. ...
