Cache and time lag

How much data are we talking about here (you say "...a very large amount..."?)

Apache can compress the output. PHP (maybe CI) can even do gzip compression. You can cache the file using a CI caching object. You can even store it in memcache or APC (or other op caching extensions.)

If those help, than do that. But the point we were trying to make is that you SHOULD NOT be storing large amounts of data client-side. Furthermore, with AJAX, you probably don't have to.

Is there any way you can get some and not all of the "tree view?" If so, all you have to do is send a query via AJAX that returns a portion of the data and then just populate that portion of the tree via javascript code (which will perform substantially better.)
