FSCache for owncloud nfs client

Hi to all, i have a question related to a possible scenario for my installation and specifically:
i have three application server (OC) sharing an nfs storage for oc-data directory and redis for php sessions container so far so good. I’m googling to add fscache agentd on every single app-server to increase performance to cache locally files. It’s a viable situation? Someone else have experience or hints/best-practices?
spec system:
3 ubuntu 20.04lts server nfs storage formatted with xfs and exported as nfsv4
