unable to get any data

[freegenie]

I'm using React 15.4.2 and I cannot get any data in the Perf panel.
I'm building with grunt, window.Perf is available in the window, I hit start, and stop but no data is collected.
Any clue would be appreciated.

Sorry. I am not sure what happened since I haven't worked on React for more than half a year. I will try to update a more user-friendly version next month.
