How do I measure if my jQuery (or JS) heavy webpage is dragging/ affecting the CPU performance of client computers (and touch devices)?
I’m not asking about load times/etc as they are dependant on the number of JS files. I’m asking about client side resource consumption and associated stability issues if any.
To be specific: I’v embedded a jQuery rotate function to perpetually animate an image, and a couple of other jquery based animated objects in the wordpress template.
You can use webkit profiler (profile, audit tab) that comes with web browsers like Google Chrome. Also extensions like page speed and speed tracer are really awesome. You can get an idea on the whole browser process like how much time it spends in UI thread, executing javascript etc.
