Slow Loading of page Mojo

Hi,

I have a Zen Mojo application that haves a tree menu, in this menu I'm loading all records from database (about 1500) and the page is very slow, about 2 seconds to load, I don't know how to get faster.

Is there any way to do this dinamically?

Because loading all in the beginning is taking too long.

I didn't find many texts around, can someone help me?
