How do distributions work and how do you prevent them?

Question

The go go tool has a profiler that can tell you the amount of the appropriations you made inside the code. However, seeing libraries like this one: https://github.com/valyala/fasthttp indicating "Zero memory allocations in hot paths" ... what does this mean? and how do you achieve this in Go?

Answer 1

I personally don’t like their use of the language, because it sounds like something a marketer would say ... All they want to say is that there will not be any allocations in this code, because the buffer was allocated in advance for use there.
