With WebAssembly Dynamic Tiering, an heuristic decides which functions of a WebAssembly module get optimized, and when the optimization is triggered. This is an improvement to the existing eager optimization approach, where all functions get optimized immediately after baseline compilation is finished. WebAssembly Dynamic Tiering reduces the resource consumption of the optimizing compiler, and prevents the compiler from competing with the web application for resources.
