A simple web benchmark of Go, Rust, Scala and Node.js.
The stats gathered by the hey tool (please run it twice for the JIT optimizations where it's applicable):
sh -c "$GOPATH/bin/hey -n 50000 -c 256 -t 10 'http://127.0.0.1:3000/'"
sh -c "$GOPATH/bin/hey -n 50000 -c 256 -t 10 'http://127.0.0.1:3000/greeting/hello'"
By default, MacOS has low limits on the number of concurrent connections, so few kernel parameters tweaks may be required:
sudo sysctl -w kern.ipc.somaxconn=12000
sudo sysctl -w kern.maxfilesperproc=1048576
sudo sysctl -w kern.maxfiles=1148576
