On: How much does Rust's bounds checking cost?

[bugfix-66]

Similarly, you can turn off bounds-checking in Go like this:

  go build -gcflags=-B

and see if it helps. Generally the assembly looks better, but it doesn't really run faster on a modern chip.

Do your own test, and keep the results in mind next time somebody on Hacker News dismisses Go because of the "overwhelming cost of bounds checking".

That’s certainly one criticism I don’t remember ever seeing.

There's a few examples like this https://news.ycombinator.com/item?id=32256038 if you search comments for "go bounds checking"

It appears that the flag keeps being undocumented, though.
