RailsConf 2019 - Profiling and Benchmarking 101 by Nate Berkopec
You know your Rails application is slow. Customers are complaining, and your ops teams are provisioning even more servers but it just isn't helping. What now? In order to fix a performance problem, you have to be able to measure it and diagnose where it is. Profiling and benchmarking are our two tools for doing just that. In this talk, you'll get an introduction to the tools available for benchmarking Ruby code, and how to use a profiler to figure out where your program spends its time.
