[Samba] Windows 7 Clients Slow/Unresponsive with some file types

I am having some unresponsive and very slow performance with a couple of
different file types with Samba and Windows 7 clients.
The problems manifest in the following manners:
    IGES files, these are CAD files. When opening up certain IGES files from
the server, the application can take upwards of 10 minutes to open up the
file. If I copy the same file from the server to the desktop, the file will
open up in a few seconds. This is most noticable with files in sizes over a
few megabytes.
    Quickbooks. Logging into the Quickbooks file can take longer than
normal, upwards of 30 seconds, instead of 5 or fewer seconds. Once in, the
application operates normally, until a reconcile action is taken. What
happens is that the reconcile action goes through, but the application
appears to be processing the reconcile for an inordinate amount of time.
This has been left sitting for upwards of 10 to 15 minutes without returning
control to the user. Killing the application and then reopening and checking
confirms that the reconcile operation was succesful. The file size for the
Quickbooks file is over 200 megabytes in size.
    I have a feeling that this is mostly an optimization issue more than
anything else.
    Any suggestions or pointers towards rectifying this would be most
    Thank you.
