Been doing some research and I found some good articles for Rails performance optimization. For those interested in such things, I thought I'd share:

• Good set of slides (once you get past some early slides) with some tips focused on different aspects of the stack: http://www.scribd.com/doc/15336193/Advanced-Performance-Optimization-of-Rails-Applications


• A short list of optimization tips (which look to have been learned the hard way): http://garrickvanburen.com/archive/optimization-tips-ruby-on-rails-and-mysql


• A not so short list of optimization tips: http://blog.pluron.com/2008/01/guerrillas-way.html


• A bit of a high-level article, but I found the three design tips insightful: http://blogs.zdnet.com/enterprisealley/?p=188


• And in general, I really liked the content linked on this site for resource on rails performance tuning: http://www.buildingwebapps.com/topic/5197-performance-tuning-for-ruby-on-rails

Enjoy. And please, share some other links if you have em.

Some time ago I met with another tester here in Indy to provide advice on performance testing. A while ago I published some articles on the notes from that meeting, and a couple months ago I published some scans of my notes from the discussion.

I don't see many examples of notes, so I thought I'd link to them here as well:

• The first page was an interactive attempt to understand the problem.

• The second page was an attempt to understand the goals of the performance testing.



• The third page was an attempt to document the initial usage model.



• The fourth page was an attempt to illustrate how I would approach organizing my work and how to present results to the various stakeholders.



• The fifth page was a description of a performance degradation curve and how to use it.
