, each test code in the code needs to be encapsulated with the PER4J library. Let's first define the number of iterations Copy Code code as follows: private static final int outer_iteration=20; private static final int inner_iteration=50000; Next, we will use the above 4 methods to implement our test code. Copy Code code as follows: String addteststr = ""; String concatteststr = ""; StringBuffer CONCATTESTSB = null; StringBuilder CONCATTESTSBU =

();Console. ForegroundColor = ConsoleColor. Red;Console. WriteLine ("filtered :");Console. ForegroundColor = color;Console. WriteLine (ws. Filter (str ));}Console. Read ();} } Output result: In addition, a simple and practical code running time test class is provided to test the running time of a code segment. Copy codeThe Code is as follows: using System; Using System. Diagnostics; Namespace WordFilter{/// /// Test code running time group class/// Public class OperationTimer: IDisposable{Pr

/200 ms to 1000 ms, respectively, because the main thread only waits for one of the semaphores to be sent, the result is output after 100 milliseconds (but note that the program is completed after 1 second, because these threads are foreground threads by default ). If we change waitany to waitall, the result is as follows: In the previous article, we used manualresetevent to implement a signal for multiple people to respond. This time we impleme

The previous blog learned how to use multithreading in a simple way. In fact, the common multithreading is really simple, but a safe and efficient multithreading is not so simple. So many times improper use of multithreading will affect the performance of the program.Let's look at an example below:classProgram {Static intnum =1; Static voidMain (string[] args) {Stopwatch Stopwatch=NewStopwatch (); //Start T

Stopwatch timing.In fact it is the QueryPerformanceCounter, queryperformancefrequency two WINAPI package, if the hardware supports high precision, call QueryPerformanceCounter, If not supported, use Datetime.ticks to calculate.Usage:Stopwatch sw =newStopwatch();sw.Start();Thread.Sleep(2719);sw.Stop();Console.WriteLine(sw.ElapsedTicks / (decimal)Stopwatch.Frequency);6 with DateTime.Now.Ticks http://www.cnblogs.com/csharp4/archive/2010/07/24/1784094.ht

, average connection elapsed 4 ms From this test, the average time to establish a physical connection is approximately 4 milliseconds per connection after closing the connection pool. Next look at the default test code Copy Code code as follows: public static void Openwithpooling () { String connectionString = "Data source=192.168.10.2;" Initial catalog=news; integrated security=true; "; stopwatc
