VB.NET Application Performance Test

Question

I am currently writing a VB.NET application and it is getting big, as a result it is becoming very slow.

Is there any application (or plug-in application) that can check performance in seconds? I mean, when I press the button and displays the product, I want to know exactly how long it will take.

Answer 1

Visual Studio (specific versions) has a built-in code profiler:

• Find Application Bottlenecks with Visual Studio Profiler

• Performance Profiling Beginner's Guide

• Analyzing Application Performance with Profiling Tools

• Visual Studio Development Team Blog

There is also a free EqaTec code profiler (works well).

[ Note : Large does not necessarily mean slow. Big recessions are often caused by code that has complexity O (N ^ 2) or more ...]

Answer 2

Built in a visual studio, this is a profiler. It can be found in the "Performance Analysis / Launch Wizard" section.

You can also download a free trial version of Ants Profiler (Red-gate.com) or dotTrace (JetBrains.com)

Answer 3

You can also use the old school trace.

Dim ts = Stopwatch.StartNew ' Your code goes here ' Format and display the TimeSpan value. Dim elapsedTime As String = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10) Console.WriteLine( "RunTime " + elapsedTime)
