Kushal1 in our case there was no sharepoint involved.
This is, what i mean: https://social.technet.microsoft.com/Forums/office/en-US/32887181-2d25-4941-b527-6f223e8b88b0/how-to-remove-microsoft-office-file-valdation-addin

"Office File Validation Add-In" is the name of the tool. It comes with windows update but stays in programs and feature. ( we have got this only with office 2010, not with o2016 or later)

Another possibility found here: https://docs.microsoft.com/en-us/office/troubleshoot/performance/office-slow-or-stop-responding

Maybe your network connection has problems and this could help.

But again, in our case there was no sharepoint in conjunktion with that.

  Rene_Gross Thank you for your response!!
  I think this office validation Add-in, now integrated as Protected View. We have already tried to disabled it.
  Also tried to disabled Micro, Add-in, ActiveX added network location in Trusted location. etc
  
  And tried the registry settings as well. But still having the same problem.
  
  We have also tried to remove the Office using removal tool and installation.
  
  I think this is something to with server. We have tried to remove antivirus. disabled firewall, adding entry in host file, disabled NetBIOS, disabled Caching . but no luck. But same things are working on newly build server.

    Kushal1 I also have similar problems and I also think that problem is in server side. Even notepad opens very slowly files from network share. File server is W2K12 R2 Std 6.3.9600 N/A Build 9600
