At Fog Creek, we converted our SSH load balancer from Python to Go. Paramiko had a number of bugs and memory leaks that were forcing us to restart it nightly. We had trouble getting patches accepted upstream over the years. Eventually, a couple of the Kiln devs decided to sharpen their Go skills by rewriting the LB. We saw lower latencies, and there was much better built-in tooling for getting statistics. Deployment was nicer. There wasn't really a massive difference, and we could have gotten the Python version to a good place, it was just easier with Go.
