It's inherent in how sync works. Over-the-wire calls are expensive.
NFS implementations try to get acceptable performance by extensive
caching, using asynchronous operations when possible, and by issuing a
smaller number of large RPCs (rather than a larger number of small
RPCs). The sync option defeats all of those mechanisms.
