Extrapolating from Techempower and from the OP's benchmarks, I got:

    137% as many req/sec as Node
    83% as many req/sec as Go

I'm it sure where this goes when you factor in async IO, but my guess is that Node gains a little and Go loses a lot.

When you add asyncpg to the mix my money is on Sanic winning by a long shot, in a benchmark that includes e.g., 3 queries and returning the results as JSON.
