CE - Slow to open files

I have a client that I have just setup to use CONNECT.  All is working well.  However, we are finding the 'File Open' speed to be extremely slow.  If we compare the open speed on the same files between V8i & CONNECT

V8i = 2 seconds

CE = 60+ seconds

OK we now have Workspaces and Worksets, but surely the speed should be faster being 64 bit.

Any thoughts;
