CONTAP-125646: Large volumes with an aggressive Snapshot or SnapMirror schedule may see degradation in IO performance or SnapMIrror transfer performance
Issue
If a Flexible volume or a FlexGroup volume with a large space footprint has an aggressive Snapshot or SnapMirror schedule set, it may see a degradation in IO performance or SnapMirror transfer performance in some situations. Such degradation may be caused by operations getting serialized on the CPU.
