A website may not always perform consistently across all devices and browser types. Site24x7 helps in assessing this performance latency with Real User Monitoring (RUM). 

Something as simple as a software enhancement or a version update could cause a spike in the response time of your web application. This is why you should track trends in your web application's life cycle on different devices (mobile phones, laptops, tablets, etc.) and browser types (Chrome, Safari, Firefox, etc.) across multiple geographies.  

These real-time user stats help you see the full scope of your application's performance so you can truly optimize it.

You can also track the response time and throughput for a particular device or browser type to dig even deeper.
