Hi there,


I had the same problem, but only on IE. Netscape takes half the time.
But 310 nodes, that's at least 700+ layers on screen... yikes!

Anyway, try using a different approach, by coding a widget yourself that
uses
just one or two layers. The whole is written on a table,
each node is a <tr><td> row.

If a node is collapsed you change the little "-" icon to "+",
turn all it's nodes invisible (by writing style="display:none;" on
the corresponding <tr> tag - yes it works on Netscape too).

You can store each row of the table in a array. That way you
can use the setHTML method to the layer each time you detect a change
(collapse/expand) and need to alter the "display" property, by rewriting
the whole table.

It still will not be ultra-fast, but it you will gain at least 2x the speed.

Hope it helps,

NunoF

I am currently loading 310 nodes in total.. and it's VERY slow..
is there any way that it can be sped up? is there anything I can discard?
only need to be able to add nodes, expand and collapse nodes, and click in a
node itself (<a href=... in title?).

it takes about 15 seconds to render (and the boss want under 10)
