Google Cloud - NetApp Volume performance

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

Hello, 

 

While trying to use the find command to traverse through the content of the volume, would it be possible to collect the output of the below command from the storage end: 

 

::>  qos statistics volume latency show -vserver <SVM_name> -volume <volume_name>

 

The above output will give us the latency breakdown for the volume and shows the contribution from each ONTAP subsystem. 

Hi @Adithya_Kameswaran 
Unfortunately since this is a Google Cloud NetApp Volume,  the  "qos statistics volume latency"  command is not available to me:
     tacoma@server1:$ qos
     -bash: qos: command not found


Do you have another way I could collect the latency data?

I tried posting this same issue on the Google Cloud forum, but no one replied. There is no Netapp support from google, so Netapp is my only option left for support.
