What it detects
Relative input timing, key interval consistency, and repeat-event patterns used to estimate polling rate.
Precisely measure input latency, key response speed, polling rate and other critical performance metrics. Designed for gamers and professional users.
• Test Method: Analyze time intervals between consecutive key presses, minimum interval reflects keyboard+system response capability
• Excellent Response: < 50ms - High-end gaming keyboard + optimized system
• Good Response: 50-80ms - General gaming keyboard
• Fair Response: 80-120ms - Standard keyboard
• Important: This is a relative performance metric, affected by keyboard hardware, USB interface, system load and other factors
Use these browser measurements as a practical reference before changing hardware, drivers, or keyboard settings.
Relative input timing, key interval consistency, and repeat-event patterns used to estimate polling rate.
High or unstable intervals can point to wireless latency, overloaded system resources, a USB hub, power saving, driver settings, or a keyboard not running in high polling mode.
Laptop keyboards pass through laptop firmware, mechanical boards may feel more consistent, and external USB keyboards are easiest to compare when plugged directly into the computer.
A browser cannot certify exact hardware latency or firmware debounce. Tab focus, OS shortcuts, background load, drivers, and USB or Bluetooth links can change results.
Phone and tablet virtual keyboards do not expose the same physical key events, so this page is useful as an explanation but should be tested with a real keyboard.
Understand the meaning of each performance metric to get more accurate test results
Measure the time delay from physical key press to system detection
Test key press to release response time and consistency
Detect the frequency at which the keyboard reports status to the system
Test results are affected by various factors including operating system, browser, USB interface, system load, etc. This test provides relative performance reference in the current environment, not absolute keyboard specifications.
Mechanical keyboards typically perform better in response speed and consistency, but modern high-end membrane keyboards can also achieve good performance. Consider feel, noise, and price when choosing a keyboard.
Competitive gamers should choose keyboards with latency <20ms and polling rate ≥500Hz. For general gaming, latency <30ms and polling rate ≥250Hz can provide a good gaming experience.
Ensure using USB 2.0 or higher interface, update drivers, enable high polling rate mode in keyboard settings, and close unnecessary system services and background programs.
This testing tool is for reference only. Test results may be affected by browser performance, operating system settings, hardware configuration, etc. Test data cannot replace professional hardware reviews; refer to multiple review sources for purchasing decisions.
For professional-grade performance testing, use dedicated hardware testing equipment and software.
