20 Jan 2016. CPU profiles, which can be visualized as a CPU flame graph, can solve a wide range of CPU usage issues. Off-CPU analysis, which can be visualized as Off-CPU time flame graphs, can begin to solve the rest. As I recently hacked stack traces for eBPF, I can now start to explore off-CPU profiling using core Linux capabilities.If this flame graph were derived from wall-time samples, rather than CPU-time samples, it could look more like the second graph below, which tells you where time actually goes: What was a big juicy-looking pile on the right has shrunk, so it is nowhere near as significant. On the other hand, the I/O towers are very wide.Flame Graph. Flame Graphs visualize the performance of your application’s code.
