As people spend more time with Ruby 1.9, JRuby, and Rubinius, we are seeing a lot more benchmarks. It has been a while since we published any metrics, so I thought now would be a good time to summarize our recent experience on some real projects. We chose to measure some different things, however:
Here's the numbers. The trends are not subtle.
DPC DPR DP5 CS5 Project A: 100% 100% 100% 0 Project B: 100% 100% 100% 0 Project C: 100% 100% 100% 0 Project D: 100% 100% 100% 0
At this point, even caring about Ruby's language performance would be a premature optimization at the business process level. Ruby's runtime performance is a non-issue for a broad spectrum of applications. In fact, I believe that all of our customers would be even happier with a language that ran 50% slower than Ruby, if it also made the development team a mere 10% more productive.
