Or turning that around, do you think it requires all 8 of my cores to copy data over the network? Do you think the two lines of code + justification text provides sufficient value for this application to distract from the point of it in order to show why someone should override the default behavior?

Do you believe users shouldn't have any control over the number of cores any particular application consumes?

Have you measured the CPU contention of the application and determined that using more cores is worth the overhead of increased overhead of multi-thread exclusions (vs. more simple things happening directly in the scheduler)?

Overall, it has nothing to do with this article and now even more people are going to copy it in more unnecessary places as a cargo-cult "turbo button" for their programs.

If you are going to use an idiom like that, the least you could do is check for the GOMAXPROCS environment variable and only do this as a default when the user hasn't specified otherwise.
