In the previous chapter, we discussed the basics of modern computer architectures—the CPU and its function, memory hierarchies, and their interplay. We left off with a brief introduction to debugging and performance analysis of Rust programs. In this chapter, we'll continue that discussion, digging into the performance characteristics of sequential Rust programs, deferring, for now, considerations of concurrent performance. We'll also be discussing testing techniques for demonstrating the fitness ...
