<![CDATA[James's Programming Page — SerialWatcherThread() taking too much CPU time? - Performance Profiler]]> 2020-07-25T17:22:19Z PunBB https://swforum.seekye.com/topic/10144/ <![CDATA[SerialWatcherThread() taking too much CPU time? - Performance Profiler]]> I've been inspecting my app for performance issues, and I was surprised when I noticed an indication that the SerialWatcherThread() is taking a considerably high CPU time in Windows. I am not sure why the profiler is pointing to the call  NativeMethods.CreateAutoResetEventOrThrow(). I understand that you have a lock inside the while() loop (WinHidManager.cs line 366) , and this thread is probably blocked. So, is that perhaps an incorrect measurement from the profiler? Also, would be nice to be able to disable those threads if I am not interested on these events.
