Start a CPU profiler in the isolate, for performance profiling. It only collects cpu profiles when the isolate is active in a thread. isolate.stopCpuProfiler(title)[Promise<Array>] Stop a CPU profiler previously started using the same title. It returns an array of profiles dependening on how...
This recipe provides configuration steps to rebuild Node.js* and enable Intel® VTune™ Amplifier performance analysis for your JavaScript code including mixed-mode call stacks containing JS frames and native frames (native code, for example, system
When many think debugging, they think your typical stepping-through-the-debugger-type interactions. However, some issues only show their face during high load. In these cases, you’ll need some way toperformance test. Myfavorite tool for performance testingNode.js isArtillery. ...
