We  are using Script.aculos.us for a quoting application.  Some of the
quotes can contain many line items.  We allow the users to group line
items and are using sortables and drag and drop to allow the users to
sort within a group and across groups.  However, it seems when we
reach about 100 line items performance start to degrade.

Also, after the user drags an item we make an Ajax call to update the
sort order and persist it.  The Ajax call returns the HTML to replace
the entire list/groups of items.  When there is about a 100 items the
display is not refreshed correctly.  It seems that perhaps the Ajax
returned HTML might be replacing a portion of the DOM that
Script.aculos.us/prototype is still processing.

Any suggestions on how to improve performance?
