Hi NetApp Experts,
I need an advice regarding the potential reason why Microsoft Office applications are very laggy when they are accesses from a NetApp CIFS share.
The file server is A700 C-dot 9.3P7. The clients are various Windows clients 7-10, 2008-2016, using SMB versions between 2.0 to 3.1.1.
The issue outline is:
- Any MS Office file is very slow to open from a CIFS share. It freezes at “downloading: ….. (0%)” and after several minutes it loads the file from 0 to 100% for seconds;
- If I open the same .xlsx or .docx with other application (notepad, Libreoffice…) it opens instantly.
- If the same file is copied locally, it opens via MS Office without a delay;
- The network speed is OK. File copy operations or opening any other file (e.g. PDF, JPEG) happens without a delay;
- I tried to open MS Office is “safe mode”, setting the network share as “trusted location”…. no improvement;
Based on the above, can you recommend what could be causing this? I’m particularly interested what operations happened behind the scenes, during the Microsoft Office is frozen at “downloading: ….. (0%)”?
Thank you!
