JetForms processing slow on new Citrix server

Question

JetForms processing on a new Citrix server running Windows 2008 R2 takes twice as long as on the legacy Windows 2003 server.  
Example invoice processing/printing: Legacy = 8-10 seconds New = 16-20 seconds.   
Printing same invoice directly from Adobe Reader takes 5.5 seconds on both servers, so it doesn't appear to be a network issue. 
Any ideas why the latency?  We are currently testing with NO antivirus software installed/enabled on the new server.

Hi Paul -- thanks again for taking time to work with me on this.   I did the DOS test and even copying a 6meg file was practically instantaneous on the new server.
I had previously reported on the 2 lines in the log file that are adding the delay.   The thing is, there are actually 8 total lines in the log file accessing the same network location.   Only 2 of the eight lines are delayed comparing new vs old server.   Here are all of the lines in order as they appear in the log file.  (There are 129 actual entries in the log, but these are the only 8 that access the C: drive location):
03/15/13 10:50:21 C:\Program Files\Adobe\Central\Bin\jfserver.exe: [307]Launching task '"C:\Program Files\Adobe\Central\Bin\jfptool" "C:\jfsrvr\Data\IN1006518.dat" "IN1006518_ds.dat" "C:\jfsrvr\jfmerge.ini" -stripport'.

... and then the last two that each take 4 seconds longer than on the legacy server:
03/15/13 10:50:22 C:\Program Files\Adobe\Central\Bin\jfmerge: [289]MDF file `C:\jfsrvr\forms\INVOICE_USER.mdf' opened.
