Share your videos with friends, family, and the world.Here's the CPU flame graph ( SVG ): Normally, the colors are picked at random to differentiate frames and towers. Red/blue differential flame graphs use color to show the difference between two profiles. The deflate_slow () code and children were running more in the second profile, highlighted earlier as red frames.Each bar, or 'flame', in the graph, is a call stack. The outermost, top-level function call (or, the 'bottom' of the call stack) is show at the top of the editor, and the functions that it calls are shown below. The width of the bar is determined by its Total Time or Total Memory.– Flame graph may sKll make enough sense • Inlining can oqen be be tuned – e.g. Java's -XX:-Inline to disable, but can be 80% slower – Java's -XX:MaxInlineSize and -XX:InlineSmallCode can be tuned a licle to reveal more frames: can even improve performance! • RunKmes can un-inline on demand
