We’re excited to announce a new feature that allows system administrators to diagnose application responsiveness problems in Remote Desktop Session Host (RDSH) with ease. We’re introducing two new counters, User Input Delay per Process and User Input Delay per Session, to give you a new way to more precisely analyze responsiveness issues.
You can use these counters, along with other metrics like CPU and Disk I/O, to find out why an application is being slow or unresponsive. The following screenshot shows an example of the counter in an overloaded system. In this example, the counter indicates that application performance across all sessions decreases as more users log in.
