vibe.d _was_ faster than Go. I redid the measurements recently 
once I wrote an MQTT broker in Rust, and it was losing to 
boost::asio, Rust's mio, Go, and Java. I told Soenke about it.

I know it's vibe.d and not my code because after I got the 
disappointing results I wrote bindings from both boost::asio and 
mio to my D code and the winner of the benchmarks shifted to the 
D/mio combo (previously it was Rust - I figured the library was 
the cause and not the language and I was right).

I'd've put up new benchmarks already, I'm only waiting so I can 
show vibe.d in a good light.
