Hi, I have a site I've recently built that makes heavy use of jQuery. One thing I've noticed since moving to the production server is that when one of the website pages is open in a browser (Safari, IE, Firefox, Camino, or Opera), the CPU usage spikes and continues to run high even after the page is fully loaded.
For example, Firefox, with the site's homepage open, will use 40-50% of my CPU (according to Activity Monitor on my Mac or Task Manager on my PC). If I close the page (Firefox or other browser stays open with other windows, etc.), the CPU usage returns to normal levels. What I am wondering is if there is a good resource for me to explore issues with jQuery and performance. I've tried Googling a series of options but I cannot find anything useful. I am sure this is because of how I coded something but am just not sure how to go about deconstructing jQuery performance so I can find the culprit or culprits! Interestingly, the CMS I built for this site also uses a lot of jQuery but does not have the same problems at all. Thank you, Craig
