Walks you through the full pipeline from perf or Callgrind output to SVG flamegraphs using Brendan Gregg's tools, then teaches you how to actually read them. Covers stackcollapse scripts, differential flamegraphs for before/after comparison, and the interpretation rules that matter: wide frames are hot, plateaus at the top are your real bottlenecks, tall stacks suggest recursion problems. The reading guide is honestly more valuable than the generation steps, since most people can make the SVG but don't know what the wide frame with narrow towers above it is trying to tell them. Includes options for consistent palettes and inverted icicle charts if you're into that.
