A panel discussion at wroclove.rb 2024 with Stephen Margheim, Maciej Rząsa, and Caio Almeida covering typical Rails performance problems, how to triage them, tools for monitoring/profiling, heuristics for when to stop optimizing, and handling large filterable index endpoints. Themes: partials are often slower than queries, understand what frameworks do, set SLAs/budgets, pick low-hanging fruit, and don't prematurely reach for Elasticsearch when Postgres with good indexes suffices.
