我正在研究电荷平衡系统,因此我需要知道每台机器的费用.PerformanceCounter似乎要走了,但创建第一个需要38到60秒.然而,每个后续的新计数器或'NextValue'呼叫几乎是即时的.

这是我正在使用的代码:

[TestClass]
public class PerfMon
{
    [TestMethod]
    public void SimpleCreationTest()
    {
        Stopwatch Time = new Stopwatch();
        Time.Start();
        Debug.WriteLine("Time is : " + Time.ElapsedMilliseconds);

        // Create

        PerformanceCounter RAM = new PerformanceCounter("Memory", "Available MBytes");
        Debug.WriteLine("Time is : " + Time.ElapsedMilliseconds + " => RAM created");

        PerformanceCounter CPU = new PerformanceCounter("Processor", "% Processor Time", "_Total");
        Debug.WriteLine("Time is : " + Time.ElapsedMilliseconds + " => CPU created");

        PerformanceCounter GC = new PerformanceCounter(".NET CLR Memory", "% Time in GC", "_Global_");
        Debug.WriteLine("Time is : " …
