gnet benchmark tools

Required tools:

• wrk for HTTP
• tcpkali for Echo

Required Go packages:

go get gonum.org/v1/plot/...
go get -u github.com/valyala/fasthttp

And of course Go is required.

Run bench.sh for all benchmarks.

Notes

• The current results were run on both Linux and FreeBSD.
• The servers started in multiple-threaded mode (GOMAXPROCS=Default).
• Network clients connected over Ipv4 localhost.

Like all benchmarks ever made in the history of whatever, YMMV. Please tweak and run in your environment and let me know if you see any glaring issues.
