Now there's a couple things I get out of this post:
- JRuby on Rails is starting, at least for this app, to surpass MRI + Mongrel for simple serial-request benchmarks. And this a week before the 1.1 beta release and all the continuing performance enhancements we know are still out there. I think we're gonna make it, folks. If this continues, there's no doubt in my mind JRuby 1.1 will run Rails fastest.
- JRuby on Rails will perform at least as well as MRI + Mongrel for the app Nick and his teammates are building. Several months ago they committed to eventually deploying on JRuby, and if you knew what I know about this app, you'd know why that scared the dickens out of me. But I'm glad the team had faith in JRuby and the JRuby community, and I'm glad we've been able to deliver.
Give it a try today, why not?
