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%)”?
Did you get a chance to narrow down this issue. We are also having a same kind of behavior with excel and documents. Infact anything related to M.office files. Open/Save/Edit any action takes forever from the NFS filesystem we are accessed via NFS Maestro.
Interestingly if you copy same files to your local desktop and open, it is instant. (very fast).
