Multithreaded Crystal initial thoughts

It would be interesting to do a similar benchmark using Go. I know Go does context switches much faster because they need to preserve less amount of registers than we do. And of course they are Google too, so…

I decided to try it out because I was curious myself. I am not a Go programmer and, in fact, this is literally the first Go program I’ve ever written, but I was able to make it work. I updated the gist I linked in my original post to include that Go app.

The Go server uses the same amount of CPU. Hope you’re sitting down for this next part:

  Thread Stats   Avg      Stdev     Max   +/- Stdev
    Latency   129.40us   91.54us   7.59ms   95.51%
Requests/sec:  69332.77

… and Crystal beats it in throughput by 56%. Feel free to check my work because, like I said, this is the first Go program I’ve ever written.
