VB.NET Application Performance Test

Question

Currently I'm writing a VB.NET app and it's getting big, resulting in its become very slow.

Is there any application (or plug in) that can test the performance in seconds? I mean, when I click a button and it displays a product, I want to know exactly how long it is gonna take.

Answer 1

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

• Find Application Bottlenecks with Visual Studio Profiler

• Beginners Guide to Performance Profiling

• Analyzing Application Performance by Using Profiling Tools

• Visual Studio Profiler Team Blog

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

[Note: Big does not necessarily mean slow. Big slowdowns are often caused by code that has a complexity of O(N^2) or greater...]
