A quick dive into the Plan9 assembly I picked up while developing my SIMD package for Go, and how it led to a 450% performance boost in calculations.

This is neat. Why do you think this is not already part of the standard library?

I think the Go std lib is focused on portability over raw performance

And ironically loses out to Java and .NET in raw performance, because language author's bias.

In this case specifically, SIMD is available, via compiler supported auto-vectorization, and intrisics, no need to go down into Assembly.
