Hands-On Concurrency with Rust

Inspecting with the Valgrind Suite

Your specific benchmarking output will likely vary but it's pretty clear that the naive implementation is, well, not very fast. What tools do we have available to us to diagnose the issues with our code, guide us toward hot spots for optimization, or help convince us of the need for better algorithms? We'll now leave the realm of Rust-specific tools and dip into tools familiar to systems programmers at large. If you're not familiar with them personally that's a-okay—we'll describe their use and there are plenty of external materials available for the motivated reader. Okay, first, we're going to need some programs that exercise our naive HashMap and the standard HashMap. naive_interpreter would work, but ...
