As someone who writes Go code that processes around 100B messages per day (which all need to be parsed and transformed), I can confirm that the author’s position is very much misguided.

And it also completely ignores the fascinating world of “GC-free Java”, which more than a few of the clients I work with use: Java with garbage collection entirely disabled. It’s used in finance a lot.

Is it pretty? No.

Is it effective? Yes.

Regarding Go’s memory arenas, do you need to use memory arenas everywhere ? Absolutely not. Most high performance code has a hot part that’s centered (like the tokenizer example that OP used). You just make that part reuse memory instead of alloc / dealloc and that’s it.

Same. I'm genuinely confused by all the comments of 'ah man, this is holding me back' in this thread, and folks claiming it's not possible to do any arena tricks in Go.

I'm not sure if these are just passerbys, or people who actually use Go but have never strayed from the std lib.
