Web page with high CPU usage -- how to profile

I have a webpage to optimize. When I enter it, the CPU usage increases drastically. I tried to use Chrome Dev Tools, but profiler 92% of the time is in the (program) line. What could I do to find the culprit of this behavior?

Please use Timeline panel. It will show you what the page does. It shows information about javascript calls, gc, layout, paint etc.
