I have a static webpage generated with a Ruby script. It uses CSS, Javascript and jQuery. When I rapidly click on some buttons in the page that are connected to jQuery events, the CPU usage goes nearly 100%. I want to see the cause of the high CPU usage, and tried Google Chrome CPU profiler, and got the following shot:

CPU profile

The high CPU seems to be caused by what is described as (program). What does that mean? And, is there a way to break down the (program) part to see in more detail which of my functions are using up the CPU?

    (program) means either (a) the tab idle time, or (b) the native browser code executed. I guess your case is (b). Have a closer look at the Timeline, and if “Recalcualte Style” and “Paint” take up considerable time, you need to optimize your page.
