perf-ninja

Why we included this project

Performance Ninja is a course for anyone who works on low-level systems code and wants to get better at finding out why things run slowly. It is built around C++ lab assignments rather than lectures, each targeting one specific problem such as a cache miss or a branch misprediction, and you spend most of your time profiling code and trying to make it faster. Once you submit a solution, it is run through automated benchmarking on Intel, AMD, and Apple hardware, so you get a real read on whether your change actually helped. The companion videos walk through each lab without handing over the answer, which keeps the focus on doing the work yourself. Teams shipping performance-sensitive services will find the exercises useful for both self-study and as a structured training program, provided everyone has solid C++ skills first.
