As of 31 December 2009

Because New Relic RPM is used by more than 3,000 organizations to manage their Ruby on Rails and Java applications in production, we have unique insight into how thousands of applications are deployed.

Since April, 2009, we have periodically published a summary of the most commonly used versions of Ruby, Rails and the various plugins deployed for Ruby applications. This report enables you to compare your own deployed application stack with those used by other development teams. Are you behind the curve in Ruby? Are there some plugins that your team may want to consider? This is a good place to start that conversation. Later this year we will publish benchmarks of the Java stacks our customers use.

Many of our customers have opted in to have their performance data shared with the Rails Core Team to aid in the team’s ongoing work on the platform. In addition to that data New Relic also aggregates information on the versions of OS, Ruby, and Rails used and the various plugins deployed.

In this report we list only the most commonly used Ruby and Rails versions and only the most commonly used plugins because a complete list is too long to post here and is probably not all that useful. This report does not cover Gems.

And without further ado…

Most Commonly Deployed Ruby Versions
(% of RPM Users)

Ruby 1.8.6 remains the most widely deployed version. That said, 1.8.7 has seen a marked increase in usage since our last report in June, going from 5% to 30% in just a few months.

Most Commonly Deployed Rails Versions
(% of RPM Users)

2.3.2 remains widely deployed as we reported in June, though most of our customers are now using 2.3.4, which was released in early September 2009. A significant percentage are also using 2.3.5, released at the end of November.

Most Commonly Used Plugins
(% of RPM Users)

While the top five plugins remain unchanged since June, hoptoad_notifiier has replaced exception_notification as the most common plugin, with over 50% of our user base having deployed it.

How to read the Plugin data: Of all New Relic customers deployed into production, X% have this plugin installed in an application. This does not represent market share or total adoption within the Rails community. It represents the percent of New Relic customers who have the plugin deployed.

UPDATE: We are now capturing the Gems deployed by our customers as well. Here is a list of the top 50 Gems in use (from a list of more than 2000.)
