A customer has recently migrated an application from one VNX to another via EMCopy
migration. The VNX’s hardware is completely identical but they have been experiencing
performance issues on the new machine. Their workload primarily consists of small random
read access to their file system.
What could be the cause of this?

A.
prefetch is enabled on the file system

B.
uncached writes are not enabled on the file system

C.
noscan is enabled on the file system

D.
nolock is enabled on the file system
