When running an instrumented binary can I use my computer for other tasks or is it better to do nothing, to get more accurate profiling data?

Hi,

The less machine does, the better the chance that results match the actual behavior of the application you're profiling. If you put more load on the machine, then you'll risk that the additional load interferes with your application and thus distorts your results.

So, it's almost always good practice to only have your application and the profiling tools running, when doing a data collection run.

Cheers,

It's what I thought.

Thank you.
