[jQuery] benchmark tool for ajax?

[jQuery] benchmark tool for ajax?

hi all,
Is there a tool for benchmarking ajax app instantly? for example,
testing the drag & drop performance?
I'm using the jquery interface plugin, the sortable plugin works well
if there's not much element inside the 'sortableitem', however, if the
sortableitem contains some more elements, the drag & drop performs
very slow, any suggestion to improve this?
TIA
Regards,
- Eric
