Can anyone explain how they go from the flame graph to identifying the function of interest net_rx_action? I can't see anything that grabs my attention, but maybe that's because the graph is too small to highlight the issues.
- Sanddancer 11y agoThe page on flame graphs [1] shows a lot more details as to how they are useful for findings like this. They gave the ten miles up view, and from there, you can click on hotspots to drill deeper and deeper and find the slow points. Cloudflare didn't give the svg, just the png, so you can't get the deeper levels. [1] http://brendangregg.com/FlameGraphs/cpuflamegraphs.html http://brendangregg.com/FlameGraphs/cpuflamegraphs.html
