I wonder whether this was at all influenced by SPARC Solaris's 8K page size. Sun was still a pretty big player in the internet and networking around this time.

I wonder whether this was at all influenced by SPARC Solaris's 8K page size. Sun was still a pretty big player in the internet and networking around this time. Or maybe it's transitive, 8K pages influenced NFS transfer size, or retrospective, NFS transfer sizes influenced page size (I don't know the history of Solaris page sizes or NFS protocols).
