First Playback often slow. SMB or NFS? (Synology)

[Iacov]

hey

my setup is:
jf in docker on a ubuntu vm on proxmox. I have my media on my synology nas. I have mounted the respective shares as smb/cifs directly to the ubuntu vm.

I'm not sure if it happens on my android devices too, but I have experienced on the android TV app (chromecast), that the first playback is sometimes slow to start.

I don't know if it's a quirk of the android TV app or a quirk of smb shares or the process of my nas having to wake up from. idle(though I don't have explicit/aggressive power saving settings in effect)

I know that it would be better to run jellyfin natively on the synology, but the cpu is aging and I wanted to offload the load to a dedicated unit. 

but is mounting via smb a valid option or does it have drawbacks I was/am not aware of? (I didn't mount via nfs, because I'm not "fluent" with fstab and didn't want to dabble with nfsv4 mounting)

maybe I'm just paranoid... but I'm trying to set up jellyfin as "family-proof" as I can and want to make sure that not my own misconfiguration causes issues
