How to Find, Debug and Fix N+1 Queries in Rails
Fixing N+1 issues is often the lowest-hanging fruit in optimizing a Rails app performance. However, for non-trivial cases choosing a correct fix could be challenging. Moreover, incorrectly applied eager loading does not work or even worsens response times. In this blog post, I describe tools and techniques I use to simplify resolving N+1 issues. [more inside]

A Call For Help - Please, Stop the Attack(s)
Hello, for the record I am banned on r/ruby and r/rails and ruby-talk for what? Now I am under (ongoing) attack on github (and reddit) and on (for two weeks going). Does anyone care? (A rethoric question, isn’t it?) For the record - Please, rethink the perma-ban policy and actually ban perma-bans. For honest people like myself (if I dare to say) who use one “doxxed” account (and no sock puppets) the system is seriously broken and in favour of misuse. Cheers.
