Treeview performances

[Paps]

I'm using a treeview control with about 30 child and sub child and about 80
elements.
The generated HTML output isn't so big (10k) but when the user try to open
the tree the first time it's very slower and sometimes happen that not all
images are loaded (so instead of the plus or minus I see the IE red cross).
How can I improve the page performances ?

thanks.
Paps

From your description, the main bottleneck is to load the images. You may
temporarily test a similar treeview control without images set to nodes, to
see if the performance is get better. If so, you may consider enhancing the
performance within the ASP.NET caching. For more information on this, you
may refer to:
