Delay in Save to/from MS Office or AutoCAD on Win8.1

similar symptoms as http://www.experts-exchange.com/Networking/Windows_Networking/Q_28356144.html

all PC's are Win pro versions on 2008R2 Domain.  Win8.1-64 / Win7-64 / Vista32
all network connections are 1Gb, full duplex.

1. FileCopy using WinExplorer shows no delay issues.  
2. Saving files from applications, MS Office (Word +Excel) and AutoCAD2015 shows noticeable delay up to 30sec
3. Saving modified PDF files from PDF-Xchange or BlueBeam  .... no issues.

Testing .... open new excel 2013 document.  type data in some random cells

1. On Win8.1 box.   SaveAs ... xlsx
  a. local file... no problem
  b. any network location on a Win8.1 / 2008R2 server or Win7 share, delay noticeable and the "saving box" is visible. for 10-20sec
  c. to the Vista32 box shows no delay.

2. On Win7 box
  a. local file  ok
  b. to 2008R2 server. ok
  c. to Win8.1 share  ... delay 17sec
  d. to Vista32  ok.

have tried turning off Receive Side scaling and large file offload in the network adapter settings. No apparent change.

will run the netsh commands to disable SMB after hours tonight.

But i cant see that saving any file properties to the NTFS is causing issues as setting DocTitle etc in PDF works without delay.
Issue appears to have become worse in last 2 or 3 weeks but cant narrow it down to any Win8 or Office update.

Any ideas as I'm copping it from frustrated users.?

Believe SkyDrive sync is already disabled as much as possible.

This will not be the protocols (smbv2/smbv3). We have that software and don't experience that.
Please take clean machines (just win8.1 with update 1 and win7 SP1, latest NIC drivers), install no anti virus. Let both have one share and test saving access from wordpad. If that works ok, take office 2013 into that game.

I have disabled the Vipre virusscanner on a W8.1 (yes, i know not quite same as delete). WinDefender is disabled as well.

I tried wordpad and it initially has no issues saving as RTF.

but when i change to OpenDoc XML, (.docx) has the delay.
OpenDocument  Text odt , has no issues.

So it only appears to be the MS Office complex file types and AutoCAD experiencing the issue.  
Both to the domain server , and to my Win7 share.  

thanks, as using wordpad isolates the issue nicely to Win8.1 and the docx, xlsx formats.

Fine, one step further at least. Now do the rest of my recommendation, take clean systems and no AV installed.

done that now.
symptom persisted in saving to network drive, but not when saving to that system.  So AV is a likely item.

we had the same AV solution on the server so I disabled active file scanning on the server  and the symptom has disappeared.  It probably should have been this way to start with as is just a file access server. (and probably was before a major version upgrade a number of weeks ago by someone else.....)

But I'm still at a loss as to why it was only the Win8.1 boxes that noticed the lag in saving. About 80% of users are still at Win7.

Any thoughts before I close the question ?
Thanks.

(Maybe) Because the AV vendor does not test thoroughly with 8.1?

while not the complete solution, certainly identified the best workaround.
