[RESOLVED] How much can I load up into the DOM?

Point #15 - under "Web Performance Best Practices and Rules" of that link - "Make AJAX Cacheable" - is what this thread is all about.

And I can happily report that you can in fact cache a huge amount of SOURCE data in the DOM at page-load time - making AJAX-calls for auto-complete's unneeded.

I've got four autocompletes that each load 25,000+ rows of data - takes a couple of seconds to initially load (but the user is unaware - as it's an AJAX call to even load the initial data!).

From that point forward the user can access those auto-completes and get full functionality without revisiting the server for appropriate data. Actually when I display a new bit of DOM with a similar autocomplete - that also needs that source data - I can effortlessly point to that object that is already in the DOM.

I am going to mark this thread resolved
