The profiler provides profiling and debugging related information without having to add a lot of programmatic overhead to the code. You only need to toggle one config setting to true and you have access to an automated tool to help create a faster and more consistent review experience. Since anyone can use it, the profiler also gives you an idea of where the code stands before the review.
Anyone who are good at English, would you please explain what does the last sentence mean? What does "stands" mean?
I assume it means "the state of the [performance of the] code", but I have to agree it's an odd sentence.
I think wat is meant is that because it is a built-in tool, anyone working on the application has immediate access to profiling information, how the code performs, without the need for external tools.
