How to check performance related issues?

[narendra]

Hi all ,
I have developed a simple application, in which I have used QLabel mainly to create my custom widget classes; say some 5-6 and used these classes to create widget which will be displayed on screen.
I can find that there is some delay of 2-3 seconds to load and display.
So my question is
How to find why it is consuming that much time?
Is there any library which qt provides or any lib or tolls I can use to find and resolve it?
Note that I draw around 50 labels on screen and I do load some 2-3 icons from resource file into labels?

Read about profiling an application and also you can have a look at Q_BENCHMARK.
