Anyone got a idiots guide for setting up fstab on my vero 4k

After having some problems with large high-bitrate files, i also looked into fstab nfs mounting.
i found this post with easy to follow instructions and it works great. I can definitely see an improvement in performance.

Reading through different posts, i noticed, that some people use “more advanced settings” as in havíng specific options like “noatime”, “rsize”, “wsize” and so on. Honestly this goes way over my head!
However it got me curious, if it’s worth looking into these options. Maybe someone can shed some light on these, point me in the right direction, or even recomment some specific settings.

To give some background, i’m using my Vero 4K via ethernet, my files are shared from a Synology DS115j using NFS and i use it to play movies ranging from ~8GB 1080p to ~ 70GB UHD.
