I have a website using jQuery that for the most part works fine, but it contains a very large form with a lot of fields. I have an option to save the settings from the form and to load and retrieve them from the server. The problem I'm running into is that the loading settings involves changing so much in the DOM (the form is huge and contains a lot of fields) that it seems to be freezing up on some browsers or timing out. I can't reproduce this on my computer (although it does take awhile to finish processing) but I've gotten enough reports of the problem that I'm looking for some advice as to how I can speed it up some.

The site is at  http://www.femaledwarf.com/ and I've tried to speed it up by caching a good chunk of the selectors I'm interacting with and I'm using IDs to access the fields in most circumstances. But I'm not sure what else I can do to really optimize the loading. Does anyone have any suggestions as to how I can go about improving on the load speed?
