I have a webpart page that has a single Data Form Webpart that is very slow. Appears from Developer Dashboard that the webpart is causing several (long executing) EnsureListItemsData calls. I am assuming that I have some DB issue - but am not sure how to debug further - any help is appreciated! This site was a SP2007 site that was migrated to SP2010. Developer Dashboard info:
