Re: Nested Tree DHTML
I have something like this (though not 215 seconds worth) and get around it by only running the nested queries when a change is made and it creates a hard page (which can be CFinserted as required) John Quarto-vonTivadar wrote: You mean the Joe Celko model?

It's gotten so large it takes 215 seconds to resolve even with the query cached! Cached queries typically don't cost time. So the problem is probably the amount of traffic over the net (HTTP compression is turned on?) or the amount of work the client side has to do. The package takes one long character string and parses it out into tables and such. Any ideas on how to speed this up? The tigra tree DHTML package looks rather complex to me. Take a look at http://www.gazingus.org/html/menuExpandable3.html for an extremely slick expandable menu.
