FTP to fast

Hello:
This is a first.   We are working with a customer on an application that we create files on IBM i and transfer to a mircrosoft server using FTP.   We've already asked and repeatedly been told FTP is the only way we can send the files.   
The job stopped working in December and it wasn't noticed until sometime later the application was not completing.  After researching and testing and troubleshooting on the IBM i and checking out the script............to no avail.  Oddly the script ran fine when we ran it manually but we could not get it to work through a submitted job scheduled to run late at night.  Everything was exactly the same for the script used to FTP when we did it manually and when the job ran as a scheduled job.  
We finally were able to get some help on the microsoft server side and the following was determined.  Working with the networking and server team to validate the following conclusions were reached.
They believe the reason the manual run works is because it was run slow.
The failure is that the server is placed into passive mode by IBM i.   And not enough is granted to get it out of PASV mode.  They were able to get the logs from a recent run from the FTP Server.   It was competing with a very large amount of other FTP traffic.  They said they cannot stress this enough we need to slow it down.  Based on the traffic from the FTP Logs and the Network capture.   The IBM i is jamming the data through.  They asked the script be changed to slow it down to fix the problem.
Following is the script used for the job
xx-de-ffm-FTPSXXXX xxxxxxxx
namefmt 1                              

lcd ..                                 

lcd /Bxxxxxxx                             

cd /DataxxxxImport/PURCH_DlvTerm           

put DlvTerm_031.txt                    

cd ..                                  

cd /DataxxxxImport/PURCH_GoodsReceipt      

mput GoodsReceipt_031*                 

cd ..                                  

cd /DataxxxxImport/PURCH_Invoices          

mput Invoices_031*                     

cd ..                                  

cd /DataxxxxImport/PURCH_Item              

put item_031.txt                       

cd ..                                  

cd /DataxxxxImport/PURCH_PaymentTerm       

put PaymentTerm_031.txt                

cd ..                                  

cd /DataxxxxImport/PURCH_PricesMaster      

put PricesMaster_031.txt               

cd ..                                  

cd /DataxxxxImport/PURCH_SettlementDisc    

put SettlementDisc_031.txt  

cd ..                       

cd \DataxxxxImport\PURCH_Supplier

put Supplier_031.txt        

quit                      



Here is the last log from when it ran in batch successfully

This is in the last GOOD FTP Log:

 

             look at next rcd~  > put DlvTerm_031.txt                                                      

         --now check for response                                                                          

             look at next rcd~  227 Entering Passive Mode (10,101,1,10,0,100).                             

             look at next rcd~  150 File status okay; about to open data connection.                       

             look at next rcd~  226 Closing data connection. Transferred 252 bytes in 1 seconds. 0KB/second.


This is a first but does anyone have ideas how to so to speak slow the job down.   We've been told FTP is the only option.
