I chuckled at "just a language change". What could be more expensive than rewriting all you code? For many Rails web apps the cost of additional servers is far

  Thus the improvements where not a result of using Go (which is is a fine language). The improvements came from replacing a bloated system with a leaner one. You can do that with many other languages. There is no magic in that.

  The cost of running 28 servers is not negligible compared to developer time. If a server goes for, say, $150 per month that's $4200 wasted each month. And contrary to the rewrite, the server cost is perpetual, so the rewrite amortises eventually. Obviously, the economics of a rewrite depend very much on the size and complexity of the code base, but it didn't sound like they had a huge code base at the time of the rewrite.
