How accurate is System.Diagnostics.Stopwatch? I am trying to do some metrics for different code paths and I need it to be exact. Should I be using stopwatc

Answer 1

Why you don't profile your code instead of focusing on micro-benchmarks?

There are some good Open Source profilers like:

• NProf
• Prof-It for C#
• NProfiler
• ProfileSharp
