Thank you for the additional information.

20 seconds to open a 460MB file is within the range of what I would
expect - even more so if the images are compressed within the file.  The
fact that only the first opening from the network drive takes 10 minutes
suggests that this is not related to file format itself.  I strongly
suspect that this ticket on our issue tracking system is the problem
that you are experiencing:

If you would like to be automatically notified of updates to that
ticket, please let me know.
