What this test checks
Estimate the rate and timing consistency of mouse movement events received by your browser during a controlled sample.
InputAnalyzer processes test events locally and does not upload your raw inputs or result values.
How to run the test
Prepare a clear movement area
Close heavy tabs if possible, enter the test area and keep the browser window active.
Move continuously
Move the mouse quickly from side to side for the full sample without stopping at the edges.
Compare several samples
Repeat at a slower speed and once more at your normal speed to see how delivery changes.
How to read the result
Observed signals, not artificial certainty.
Stable browser delivery
Repeated runs at a similar movement speed produce comparable event rates and interval distributions.
Irregular delivery
Long gaps or large changes can reflect browser load, power saving, movement speed, drivers or the device itself.
What this test cannot prove
What the browser cannot see
- The result is not the mouse's guaranteed USB polling rate; browsers may coalesce, throttle or reschedule events.
- Movement speed, display refresh, system load and power settings all influence the observed rate.
- Results are browser-based estimates, not a physical hardware diagnosis.

Frequently asked questions
Short answers before you test again
Is event rate the same as polling rate?
No. Polling occurs below the browser. This page counts movement events after they pass through the device, operating system and browser.
Why does moving faster increase the result?
Browsers may deliver fewer events when there is little movement. A fast continuous sample gives the event stream more opportunity to reach its observed ceiling.
