Flame Graphs and Continuous Profiling: Visualizing Performance at Scale
Flame graphs visualize sampled call stacks: wider bars = more time spent. Continuous profiling captures these samples always-on in production, enabling post-hoc analysis of performance incidents. This guide covers reading flame graphs, differential (diff) flame graphs for comparing before/after, and setting up Pyroscope or Parca for continuous profiling.
