Off-CPU Flame Graphs. Off-CPU Flame Graph. On-CPU performance issues can solved using CPU Flame Graphs. That leaves off-CPU issues: the time spent by processes and threads when they are not running on-CPU. If this time is spent during an application request, synchronously, then it directly and proportionally affects performance.This can be visualized as a flame graph, where the x-axis spans the total blocked time, and the flame graph shows the blocking code paths. As the entire profiler output is visualized at once, the end user can navigate intuitively to areas of interest. The shapes and locations in the flame graphs become visual maps for the execution of software.
