I've found the network plays a huge part in the time it takes to update data shortcuts. I think you have to look to optimizing the network rather than C3D. For instance in the office I work in we have a WAFS and if the a referenced file is opened in a different office it takes the project a considerably longer time to load since the WAFS is checking repeatedly to see if it has the most recent version for each and every data shortcut in the file (C3D opens and closes the file for each DS instead of opening it just once).
