Description
I have a tree structure of 120 nodes, 2 layers.
The view takes too long to draw itself, actually I tried this in IE, Firefox, and Chrome and it takes about 4 minutes to draw all the tree, making the browser to warn about a js script (jquery) that looks to be freezed. Aftet this time eveything is correctly displayed on the screen, but whenever I click on the arrows to expland or collapse, it takes the same amount of time to re-order the view.
I am using the latest version of Drupal 6. For this module I tried with both last release and last devel versions, and the result is the same.
Is this a limitation issue with the module itself or with my local installation.
Thanks.

I've created a big view http://sevi.zites.net/drupal/big for testing.
The page needs approximately 13 seconds to apply all javascript behaviours. For 1 out of 6 loads a the browser freezes and a javascript-warning-message pops up.
After the page is loaded I can drag, expand and collapse nodes immediately (600 milliseconds slower than expected).
I'm using a MacBook Pro, 2,53GHz, 4GB RAM; Mac OS X Snow Leopard, Firefox 3.5.3.
I guess it is the expand/collapse javascript of DraggableViews that slows things down. When I disable expand/collapse (Show expand Links=No), see http://sevi.zites.net/drupal/big2, the page and the javascript tabledrag behaviour loads within 4 seconds.
Try to disable expand/collapse on your site too. The expand/collapse javascript probably could be improved one day to gain more performance.
EDIT: From 2 to 4 seconds.

OK, thanks for your prompt response.
Disabling expand/collapse solved the slowness, but having a 120 nodes tree without that option is really a mess.
I'll close this one.
Thanks.
