Applies to

• FAS
• AFF
• NetApp Cloud Volumes ONTAP
• NetApp ONTAP Select

Description

• This article is a starting point for understanding where a performance problem may be, and identifying other articles to help resolve the problem.
• Performance issues are typically:
  • Job run time is longer than expected or job time is delayed
  • Slower than expected throughput
  • Higher than expected latency
    • High read latency, high write latency, or high other latency is seen on the client/application side or ONTAP side
  • Utilization is higher or at 100% of a processing center (CPU/disk)
  • Slowness on SAN or NAS, or slowness with CIFS, FCP, iSCSI, or NFS
  • Sudden increase in latency, possibly due to increase in IOPs or workload
  • Slow backups
  • Degraded or poor performance
