How to know which instruction taking the longest time to finish ? (to increase my program performance)

Question

I need to know how can I get every instruction's duration so I can maintain the code to increase the performance of my program .

Answer 1

Use a profiler. If you have Visual Studio Team System, there's one included. Otherwise take a look at ANTS or dotTrace.

Answer 2

what you're looking for is a profiler I believe :)

see: Profiler and List of Performance Analysis Tools

Answer 3

You want an application profiler for that, it shows exactly what code takes how long.

Answer 4

You need to use a profiler to accomplish this. It exists several profilers, some are free.

My preference goes to Red Gate Ants.
