Some libraries may have hundreds of open orders for a vendor, depending on acqisitions workflow. At that number of open orders, the tables on parcel.pl take 10 to 20 seconds to load.
To speed up the loading of this page and the data, we should convert the order tables from pre-loading all order data to ajax tables that load order data on an as needed basis. That way we are only pulling the data for the orders that are currently visible.
Was a bit confused by the bug title - hope I made it a bit more clear.
