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. mike
