Overview
The Memory Test measures your browser's memory allocation and bandwidth capabilities using a series of benchmarks. It runs in a Web Worker to keep the UI responsive and uses WebAssembly when available for results closer to hardware performance.
Results reflect browser memory bandwidth, not raw hardware speed. The browser's memory allocator, garbage collector, and security sandboxing all influence throughput. WebAssembly benchmarks run with less overhead than JavaScript but are still mediated by the browser runtime.
