> * If Crystal is compiling to smaller binaries that run faster in a basic test without a lot of optimization and configuration tweaking, you can imagine that that relationship will hold true in larger codebases as well.*

Why would that be the case? I see no correlation. The two programs in the article were little more than glorified "hello, world" samples.

For all we know, Crystal might accumulate binary code cruft much quicker than Go as the project grows.
