Re: XSL taking very long

The XML provided doesn't have a Category element...

You probably shouldn't be using //vform which translates to
/descendant-or-self::node()/child::vform and causes the entire node
tree to be searched for vform elements from the root to the deepest
leaf. Depending on your context you probably just need vform, or
perhaps /Search/SearchResults/vform.
