마우스 폴링 레이트 측정 (브라우저 이벤트 Hz)
브라우저가 마우스 이동 이벤트를 수신하는 빈도(Hz)를 측정합니다. 약 125Hz에 고정된 문제를 찾는 데 유용하지만, 실험실급 USB 측정은 아닙니다.
What is Mouse Polling Rate?
Polling rate measures how often your mouse reports position updates, expressed in Hertz (Hz). A 1000Hz mouse sends 1000 updates per second, providing smoother cursor movement and lower latency—crucial for competitive gaming. This browser-based test measures your mouse's actual polling rate with no software installation, showing median, peak Hz, and stability.
How This Online Polling Rate Test Works
Our polling rate tester measures the time interval between mouse movement events in your browser. When you move your mouse, each position update is timestamped with high-precision timers. By calculating the frequency of these updates, we determine your effective polling rate in Hz. We also show distribution patterns, median values, and stability scores. All processing happens locally—no mouse data is sent to servers.
Accuracy and Limitations
This browser-based test accurately measures polling rates up to approximately 1000Hz for most scenarios. However, there are limitations: Browser event handling introduces some variance. Very high polling rates (2000Hz+) may not measure accurately. System load and compositor timing can affect readings. USB hubs or power saving may throttle rates. For lab-grade precision, hardware USB analyzers are more accurate.
How to Interpret Your Results
Polling Rate
125Hz is standard for basic mice, 500Hz is common for gaming, 1000Hz is high-performance. If expecting higher but seeing ~125Hz, check mouse software or USB power settings.
Stability Score
High stability means consistent polling intervals. Low stability with erratic readings may indicate USB issues, power saving throttling, or system interference.
Distribution
The frequency distribution shows how consistent your polling is. A tight peak indicates stable polling; a wide spread suggests inconsistent intervals.
