[Solved] Find how many cores are being used by a c# application

Question

It’s difficult to get a precise answer without using specific performance monitoring tools, and it does vary moment to moment.

I’d suggest using Perfmon while running your application as a starting point for your analysis. If you’re using certain versions of Visual Studio, you can also try Analyze | Performance Profiler.

If you want a quick and dirty – run your application and look in debugger or task manager. If you’ve got a 4 core/thread processor, you’d expect to see around max 25% of your CPU being used if you’re only utilising a single thread with your code.

Look into concepts such as Async/Await and Task Parallel Library if you want better utilise the available processing power.
