Flamegraphs

Flamegraphs are visual tools used to understand how a computer program spends its time. They display functions or parts of the code as horizontal bars, stacked to show call relationships and timing. The wider a bar, the more time that function takes. This helps developers quickly identify which functions consume the most resources or cause slowdowns, making it easier to optimize performance. Flamegraphs present complex data in an intuitive, layered chart, allowing for rapid insight into where a program might be improved or troubleshot.
