I don't know about others but I avoid DateTime.Now not because it's inefficient but because it is plain wrong to use it to measure durations. Or more generally, to use it for anything that doesn't involve … WebIf the installed hardware and operating system support a high-resolution performance counter, then the Frequency value reflects the frequency of that counter. Otherwise, the Frequency value is based on the system timer frequency. Because the Stopwatch frequency depends on the installed hardware and operating system, the Frequency value …
