![]() ![]() Next, see the User Input Delay per Session. The maximum scale is set to 100 (ms) by default. The counter starts reporting user input delay as soon as you add it. You won't see any processes that are running as SYSTEM. To use these new performance counters, you must first enable a registry key by running this command: reg add "HKLM\System\CurrentControlSet\Control\Terminal Server" /v "EnableLagCounter" /t REG_DWORD /d 0x1 /f NumberĮnable and use the new performance counters The counter reports this delay because the user's perception of "slow" is determined by the slowest input time (the maximum) they experience and not the average speed of all total inputs. ![]() The counter reports the slowest user input delay in the interval. This delay is the longest time it takes for an input to reach the application, which can affect the speed of important and visible actions like typing.įor example, in the following table, the user input delay would be reported as 1,000 ms within this interval. One important detail of this counter is that it reports the maximum user input delay within a configurable interval. A traditional message loop is shown in the following flow chart: The User Input Delay counter measures the max delta within an interval of time between the input being queued and when the app in a traditional message loop picks it up. The following image shows a rough representation of user input flow from client to application. The counter works in both local and remote sessions. ![]() This counter measures how long any user input, such as mouse or keyboard usage, stays in the queue before a process picks it up. The User Input Delay counter can help you quickly identify the root cause for bad end user Remote Desktop performance experiences. The User Input Delay counter is only compatible with: ![]()
