More efficient pg_restore method?

Pg 9.6.9 on Linux...

Given a backup server storing a "format=directory" database backup, and a 
database server, should I:

Option #1: run pg_restore on the backup server and "push" the data to the 
database server via port 5432, or
Option #2: have the backup server serve the dump directory via NFS, and run 
pg_restore on the database server, pulling the data via nfs protocol?

(It'll be a multi-threaded restore over a 10Gb pipe.)
