Folder in CIFS share takes long time to list files
Applies to
- CIFS
- ONTAP 9
- Windows
Issue
- When accessing the problematic folder from the CIFS share via the mapped drive in Window Explorer, it takes ~40 seconds to list the content of multiple thousands of files.
- Sometimes the Windows Explorer greys out and states
not responding
, but eventually loads the content. - Other folders on the same share with similar numbers of files may not be affected.
- When tracing the access, there is no unexpected roundtrip time/latency observed.
- When accessing the problematic folder directly via UNC (RUN (Windows-key +R):
\\share\folder\
), it lists files in a few seconds.
