Hello everyone.

I currently use perf to get stackframes of my application to improve the performance of it.
But in this issue: #148

1. perf(1) support is now deprecated in V8 and will not be supported starting in Node 8 -- which effectively means we’re losing the ability to profile JS stacks.

Is perf already deprecated? How I can still get the stackframes and generates graphs of CPU profiler without perf?

Thanks!
