Displays browser memory usage and device RAM. Run the allocation test to measure memory write speed.
The performance.memory API is only available in Chromium-based browsers (Chrome, Edge, Brave). Firefox and Safari do not expose heap memory information. You can still run the allocation speed test below.
Modern browsers expose limited memory information through the Performance API. The performance.memory API in Chrome provides insight into JavaScript heap usage, while the Device Memory API allows websites to adapt to different RAM configurations. These APIs help developers optimize web applications for a range of device capabilities.
The allocation speed test measures how quickly your system can allocate and write to a 50MB block of memory, which is a proxy for memory bandwidth — an important metric for applications that process large datasets.

A data-backed look at 100 gaming mice across 125Hz to 8000Hz, with stability notes, real-world limits, and how to compare your setup using our mouse polling rate test.
A 2026 roundup of hardware testing tools, from browser-based no-install checks for mice and screens to GPU stress tests and system monitoring.
Web-based mouse polling tests measure browser-delivered pointer event frequency, not raw USB polling. Learn why ~125Hz appears, why high polling rates are indistinguishable on the web, and how to interpret results.
