Windows 7 Pro 32 bit file synch running slow

I have a laptop that uses offline files in Windows 7 Pro. It has been working fine for a year or so.  Lately when the user comes into the office and logs in, the sync of the offline files is taking 45 minutes when it used to take less time.  

When I look at the results in Sync Center, the actual sync time shows as 15 minutes or so.  I'm not sure what it is doing for the first 30 minutes while sync icon is spinning in the tray .  

Access to the server share the files are located on is fast.  Using gigbit switch and gigabit card in laptop.  I do not see anywhere in Sync Center to adjust the settings.

Any help is appreciated.

 Thanks,
cja

You can try disabling autotuning to see if it improves the speed.  From an administrative command prompt run:

netsh int tcp set global autotuninglevel=disabled

It changes the settings for the TCP receive window to not automatically adjust ( http://en.wikipedia.org/wiki/TCP_window_scale_option ).

You can revert the setting if needed by running:

netsh int tcp set global autotuninglevel=normal
