I've got several users who operate in a manufacturing environment. Two different users use this particular Excel file, which has SQL query set up to pull from a server. 

After setting up user A with a new workstation (Office 2013, windows 7, restarts & patched), his system takes approximately 20-30 seconds to perform a Data Refresh of a particular tab. It takes approximately this long for most Office 2013 installs to accomplish this that i've tested. This same function is accomplished in 1-2 seconds in office 2007 on any computer. 

I do have a user B who is on excel 2013, and the data refresh happens almost instantly. I've checked the trust center settings, options/advanced, and the file itself - I can't find any differences between his workstation and the others. I've tried disabling hardware acceleration, multi-thread calc, and some random other things without success.

Any suggestions for settings that could cause this? Below is the connection information.

No ideas?
