on my same machine, go.d:

received 100000000 messages in 2906 msec sum=4999999950000000 
speed=34411 msg/msec

so, it's ~2.7x faster than Java:

And your https://github.com/nin-jin/go.d on my machine

go.d is 2~4 times slower than Go.

9.7638ms (Go) v.s [19 ms ~ 40 ms] (go.d)

Go's speed is consistent in multiple runs, for go.d it can be 2x 
difference, maybe because of the scheduler is unstable?

It's not mine, but @MartinNowak's.  The implementation is based on
