How to measure UI latency?

This can be done non-programmatically by manually recording those times, or programmatically by getting a timestamp immediately before you begin some action, then a timestamp immediately after the action completes, then taking their difference. That time difference is the application's UI latency for that action.

How to measure application latency?

The most accurate way to measure latency is by using a Network Monitoring Software, like Obkio. That's why a tool, like Obkio Network Performance Monitoring software, continuously measures latency by sending packets every 500ms to catch latency issues affecting VoIP, UC applications and more.

What is latency and how is it measured?

Latency is measured in milliseconds, or during speed tests, it's referred to as a ping rate. The lower the ping rate the better the performance. A ping rate of less than 100ms is considered acceptable but for optimal performance, latency in the range of 30-40ms is desirable.
