Evio with SO_REUSEPORT

Using the reuseport branch of evio, you can now provide an SO_REUSEPORT address options from the Serve function.

evio.Serve(events, "tcp://0.0.0.0:5000?reuseport=true")

This allows for multiple process/threads/goroutines to share the same address+port.

You can try it out using the echo example. Run this in seperate terminals:

go run examples/echo-server/main.go -reuseport -trace

Then repeatedly send a packet from a different computer:

echo hello | nc hostaddr 5000

You should see the message "hello" print to one of the two server consoles.
