Non solo di prestazioni, apt-cache show ti spiega un po' di differenze:

Description: Kernel NFS server support
 Use this package if you have a fairly recent kernel (2.2.13 or better)
 and you want to use the kernel-mode NFS server.  The user-mode NFS
 server in the "nfs-user-server" package is slower but more featureful
 and easier to debug than the kernel-mode server.

Description: User space NFS server
 This package contains all necessary programs to make your Linux machine
 act as an NFS server, being an NFS daemon (rpc.nfsd), a mount daemon
 (rpc.mountd).
 .
 Unlike other NFS daemons, this NFS server runs entirely in user space.
 This makes it a tad slower than other NFS implementations, and also
 introduces some awkwardnesses in the semantics (for instance, moving a
 file to a different directory will render its file handle invalid).
 .
 There is currently no support for file locking.
