Should fasthttp be used in production? It seems to get a lot of flak for not fully implementing HTTP.

Like every engineering decision it is a risk/reward spectrum. But unless you have profiled to know that net/http is your bottleneck, no, you should almost certainly not use fasthttp.

We use it in production, though fair warning we have very limited endpoint and consumers that allow us to test it aggressively.

What I really meant is we'd need to take things down to the bare network stack. Lots of our memory use/bottlenecks are fairly deep into the std lib.
