Only thing I have installed is Nodejs. I'm using Windows 8 x64.
I run my program via node --prof app.js. It generates a v8.log file.
Now, what do I do with the v8.log file?

V8 CPU and memory profiling Last modified: 25 July 2022. With WebStorm, you can capture and analyze CPU profiles and heap snapshots for your Node. js applications using V8's sample-based profiler. You can also open and explore snapshots captured in Google Chrome DevTools for your client-side code.
The V8 engine is what powers Node. js and it is an open-source engine on which even Chrome works. It parses and runs your JavaScript inside a Node environment.
Node. js profiling allows you to use the profiler already available to you (--prof) through the Node. js program and discover performance-related issues within your application. With this profiler, you'll be able to delve into the performance of your application and find what's causing bottlenecks.
No. The current node. js binary cannot work without V8. It would have no Javascript engine and thus no ability to run code which would obviously render it non-functional.
Starting with v5.2.0, Node.JS ships with a built-in tick processor:
node --prof-process
See the release notes for more information.

Chrome's built-in Trace Event Profiling Tool (accessible in Chrome or Chromium at chrome://tracing) can build more-useful visualizations around v8.log output.
Note that dumps from node >= 0.11.x may be more useful to you than those on the current stable release (0.10.35).
