What are the main suspects in a really slow Rails app?
N+1 requests are an easy first step. Bullet gem works, but is overeager. I prefer Prosopite for this task (https://github.com/charkost/prosopite)

Is there a more efficient way to do these permutation calculations?
Either https://github.com/tmm1/stackprof for cpu or https://github.com/SamSaffron/memory_profiler for memory. In practice profiling and removing allocations also gives a large perf boost.
