Performance Profiling a Mongoid Issue Using AppProfiler
While doing research on Ruby profiling I found Shopify's blog post on "How to Fix Slow Code in Ruby". Though the entire post was extremely insightful, it lead me to Shopify's app_profiler library, which can be used to automatically profile code and redirect the output to a local instance of speedscope. Having worked previously with Flame Graphs of CPU stack traces collected using perf.

A Trick For Reading Flamegraphs
Flamegraphs simply visualize this process by placing each of these recorded stacks side by side. The resulting visualization looks like "flames", hence a "flame graph". If you do this visualization where the "parent" of all the stack frames is on the top, rather than the bottom, you get a "waterfall graph", because it looks like a waterfall. It's the same thing though. Speedscope and DevTools visualize using the waterfall format, but I still call them flamegraphs anyway.
