Slow reads on a CIFS share (no issues with writes)
Applies to
- ONTAP 9
- CIFS
Issue
- A read activity is much slower then a write activity on a CIFS share
- End users are reporting low throughput (poor performance) by read activity (slow read) on a CIFS share
- Data ONTAP and NetApp monitoring tools reports no relevant information
- Packet trace (tcpdump) between CIFS-server and -client reports issues on read activity on client side: small payload, packet drop (loss), server side is fine
