Accredo saturn database slow login for user

We have a company that has a financial App called Accredo Saturn , Its an install on the fileserver
What it uses are Database files called "PDB" and  "PNX"   Users connect to this via an exe on their local laptops/desktops win7 .

everytime a particular user (user A) logs in 1st other people are having slowness issues
Running wireshark
there are Lock requests going to the fileserver where the files are hosted but no Oplocks
Server = Server 2012
Workstations win7

I have done a lot of investigation on this and troubleshooting even seen some readups on this similar to FOX pro DB`s
What we have done was to try and patch the server with http://support.microsoft.com/kb/2957623 
1.      Remove redundant entries from your PATH statement, specifically any drive mappings that may no longer exist.
**If there were Mappings at a stage that changed or could still be mapped for Sue can we check to tidy it up
2.      Finally, and most productive for me, disable Interrupt Moderation in the advanced settings of your network card.
Reinstalled the particular App to a different Directory

Even Contemplating turning off SMB2

are you saying that as long as user1 is not using the software, user2 and user3 have no problems accessing the software?  but when user1 logs in user2 and user3 suffer slowdowns?  Does it use a SQL database or a flatfile database?
JakesCAuthor Commented:
Hi there

1. Correct: RE user scenario
2. They are using a Flatfile database not SQL
