But on ONTAP 9.5, it has been observed that SCE performance is degraded and it only provides a similar throughput as Block Copy Engine(BCE). The majority of the delay comes from a long suspension on COPY_WAIT. Note: In this case, average Suspend time on COPY_WAIT is about 120.78ms. The WAFL suspension stats could be viewed from any Perfstats, or collected in a manual way:
