"In tasks that require only small amounts of communication between nodes, the performance advantage of high-end hardware is limited."

You've misread the graph. It's more: if your application requires large amounts of communication, the benefit of high end hardware is limited.

And: in larger clusters, large amounts of communication is near inevitable, eliminating nearly all performance advantages of high end hardware.

👍

Was going to file this same issue.

Thanks for reporting this! Yeah, this was inconsistent/incorrect. The text below states Even in tasks that require high amounts of communication ... Fixed in 49893fc with text that I think is more descriptive, but let me know if you would change it further.
