Copying millions of files within a volume

[TimJMcCuen]

Hello,

I have a customer that ingests millions of small files into a netapp volume and then copies the data to another directory in the same volume.  Sometimes my customer experiences latency when copying the files.   I don’t see volume or controller latency.  I would think the files are already in cache / WAFL when the files are initially ingest therefore the write to another directory would be fast?   Is there a way to remedy this?    would NFS trunking be a solution?

The environment

FAS 8300 controllers running Ontap 9.15p7

Linux servers running RHEL 9
NFS v4.2

Thanks

Hello,

The latency happens during the first copy or during the second passes ?

The tool is only "CP" commands ? 

Wath is the tool to check the latency ? System Manager ? have you try NABox ?
