Inconsistent share access speed

[m0ngr31]

I have a share that I have all of my development work in that lives on my cache drive. One of the projects is a Node program that is compiled with webpack. I noticed that when I try to run this via docker vs VM, the results are quite different...

 

I setup some different use cases to figure out what is going on. My docker container and VM are both running Ubuntu 18.04

 

Docker Container:

• Project running from share passed in as a volume: Takes ~160-180 seconds to finish running.
• Project running from local docker fs: Takes ~50 seconds to finish running

 

VM:

• Project running directory mounted from NFS share: Takes ~90-100 seconds to finish running
• Project running from local VM ssd (unassigned device): Takes ~70-80 seconds to finish running

 

I would have imagined that the docker volume would be faster than consuming the share from NFS, but maybe I'm doing something wrong? Has anyone else noticed how a discrepancy this bad?
