NFS, designed as stateless (all operations are synchronous), is not really
fast, itself. And having to emulate file metadata operations that are
designed into AppleTalk/AppleShare does not make it any faster.
The overall consensus seems to be that supporting the clients' native
network protocols on the server side (Samba, Netatalk) works out better
than mapping network protocols on the client side (to NFS, SMB, whatever).

No. Even the Open Source NFS server project for the Mac was cancelled.
