I have read most of the articles out there regarding Rails performance<\/b>. Performance-minded railers list fragment caching, normalize database design, proper use of indices, and the exclusion of unnecessary columns from large tables in active record models as providing a beneficial performance boost for any Rails application. These railers also warn against excessive use of route url recognition and generation, eager loading, and slow application helpers.<\/p>\n
The following list is a collection of the best articles, blog posts, presentations and discussions on Rails performance. Feel free to add any site that I might have missed in the comments!<\/p>\n
