I am not sure if this is the correct forum, but I did see other posts about NetApp volumes here. Please advise of the correct forum if needed. On the Google Cloud Platform, I deployed  a STANDARD service level 2048gb NetApp storagepool in uscentral1. Then I created a 100gb volume also in uscentral1.   I have a question about this volume's performance. When I use the FIND command to traverse through a directory, the performance is noticeably slower on the Netapp volume versus the same data on the local drive. At first I was thinking I needed to increase my throughput performance by increasing my service level or making the volume bigger(which increases throughput performance). But after thinking about it, my FIND command is not moving data, it's just traversing through the directory. So it seems this is not a throughput issue?   Does anyone have insight as to the performance issue here:   root@server1:~# time find /data_local/cache/4c71-4cb6-bd50-d80aa7/ -type f | wc -l 4995 real 0m0.119s user 0m0.058s sys 0m0.059s root@server1:~# time find /data_NetappVol/cache/4c71-4cb6-bd50-d80aa7/ -type f | wc -l 4995 real 0m3.968s user 0m0.078s sys 0m0.219s ...

Hi Team, I recently created an NVMe Namespace, and during the process, an associated volume was automatically created. Below are the details: NVMe Namespace Path: /vol/namespace_nvme/namespace_nvme_1 Associated Volume: namespace_nvme I’m trying to understand the performance differences between the NVMe namespace (/vol/namespace_nvme/namespace_nvme_1) and the associated volume (namespace_nvme). Specifically, is the performance of the NVMe namespace the same as that of the associated volume, or are there key differences in how each performs? Looking forward to your insights! Thank you! ...
