Bandwidth needs halved by new compression written in Go
The title suggests that there's something unique about Go, either the language or its standard library, that enables bandwidth savings.  In fact, Cloudflare have written some software which they claim enables them to reduce their bandwidth, and this software happens to be written in Go.  This might be an excellent choice (and I suspect it probably is), but it's not <i>Go per se</i> that is reducing the bandwidth usage.
