Using IIS7 for FTP ,when using a UNC path in the virtual directory to a network share, file transfer speeds are slow

We are running the following:

Windows Server 2008 R2 with IIS 7.  
We are using IIS7 for our FTP server.  The virtual driectory  in IIS is a unc share which is on a 5 year old ish EMC storage array. The server and array are plugged into the same switch.  When a user connects to the FTP server to download files from this path the transfer is very slow.  If the virtual directroy is local the speed is fast.
The FTP server is in a single domain and there is no firewall between the FTP server and the shared storage.  Because of the large numbers of FTP files and size of the files we can't store them locally on the FTP server.
I realise it is probably SMB causing this, is there any thing specific we could do to speed up the transfers.  Also if we changed our FTP solution to something that wasnt IIS is there a product out there that would provide fast transfer speeds to UNC storage paths, by bypassing using SMB protocol.  All of our infrastructure is a mixture of Windows server 2003, 2008 and windows 7 and XP clients.
Thanks

Does the array support CIFS or can you mount a LUN from the array directly on the IIS server instead of access it via a UNC share?

Yes the EMC supports CIFS, the array supports mounting a LUN, but we don't have any spare ports on our fibre switch, so we currently can't do that.

If you are on a Windows system then you are gonig to use the MSB protocol to access a UNC share.  That's not a function of the program it's a function of the OS.  From a programming standpoint the conenctivity is being provided by the OS no reason to reinvent the wheel.

If you connect to the share from another server is the connecvity to the share as slow?  If you connect directly to the share from the server with IIS on it is the conenctivity as slow.  You can probably tune your devices some but you need to know where the pain point is to perform the tuning.
