CVO == Cloud Volumes Ontap, the software version of OnTap that you can run in the various CSP's (Cloud Service Providers) aka GCP, AWS, Azure
https://cloud.netapp.com/ontap-cloud
PD == Persistent Disk, what GCP (Google Compute Platform) calls its, uh, persistent disks.

And to answer Jeffs question, we've not done any CVO testing in GCP, so I can't answer the throughput questions.
We have found that, in general, the VM Instance type that hosts the CVO instances matters, since the Instance type also determines networking connectivity.
Disk type (in this case GCP PDs) matters, too; I'd test with Local SSD to see where that gets you.
Lastly, Throughput is dependent on workload, which determines the IO pattern. Maybe create an FIO config that generates traffic close to what you expect, and use that to drive various CVO configurations.

Jeff, I know you're deep in the weeds, but for those of us who aren't... can you spell out those acronyms please?
PD = Purple Dinosaur? CVO = Cheery Victory Orange?

Yeah, you need to translate this section as well please. Or at least give a little more context so people have a hope of understanding. Or better yet, learning from your experiences!
