We have recently updated BitNami RubyStack to include FiveRun’s TuneUp This module allows you to do performance tuning of your Ruby on Rails app before you put it into production. TuneUp was developed by FiveRuns and is a free application profiling tool for Rails and Merb developers. It makes it fast and easy to troubleshoot and spot bottlenecks in your app, and even provides a way for you to collaborate with other developers who may be experiencing similar problems.
Download RubyStack to check it out. Let us know in the forums of other modules you would like to see included in future releases of RubyStack
