node bindings for the v8 profiler, minus the retain/dominator bits removed from V8
npm install v8-profiler
We now include node v0.10 binaries for a number of platforms. During the install, node-gyp will attempt to build the module for your platform. If it fails (see builderror.log), the module will still be installed, but will attempt to load up an appropriate pre-built binary for your platform if there is one available.
var profiler = require('v8-profiler');
var snapshot = profiler.takeSnapshot([name]) //takes a heap snapshot profiler.startProfiling([name]) //begin cpu profiling var cpuProfile = profiler.stopProfiling([name]) //finish cpu profiling
Cpu profiles can be viewed and heap snapshots may be taken and viewed from the profiles panel.
