I updated the article in two plaes with the following text:

As user @heppu points out Go’s stdlib HTTP server can be 12% faster than the graph shows when written more carefully. Also there is the awesome fasthttp server for Go that apparently is only 18% slower than Japronto in this particular benchmark. Awesome! For details see #12 and #14
