Go is slow garbage, best upgrade to a better lang.
Discussion
if every ounce of perf matters use C or rust. otherwise, Go is a great language that is very easy to write and has excellent primitives for concurrency and web services. Id venture to say 95% of the time Go speed is not a problem. most code projects dont need to manage memory themselves.
exactly... rust, c and c++ can give you an extra 10-20% throughput
but none of them can give you the low response latency of Go, no matter what you do
that's the thing, what matters more?
unless you are converting video files (without a GPU???) or some other equally long running computation, their advantage is nil to negative, because of the time cost of development and the far harder debugging process
rust is an overly complicated, slow compiling piece of shit, best to downgrade to a smaller, simpler lang with a proper garbage collector instead of one that takes 6 months to learn how to annotate your variables for it, and forces you to explicitly make everything mutable which is almost everything, unlike C which you can only make immmutable by using static
people make their tradeoffs and i prefer to be never able to do much better than 80% performance as Rust when it takes me 20% of the time to write the same code without bugs
