Benchmarking Go programs, part 2

There were a couple of things that didn’t make sense to me initially in terms of optimisation of Go code. I’m going to try to list some of them that I found more interesting and you should be aware of this if you’re really working hard to optimize your Go program for performance or memory usage.

Benchmarking Go programs

Benchmarking is an important step in writing software. This may extend beyond the scope of your Go program, but attention should also be given to the Go program itself. If you’re writing APIs or if you’re implementing a parser for a specific file format - benchmarking will tell you how performant your implementation is.
