Yup, that sounds correct. Here's my script that's a wrapper for dd doing a write test over NFSv3 from a dell precision 690 on a gigE link to a dell poweredge 2950 also on a gigE link with two 7200 RPM SATA drives in a RAID1. These are two systems that are across campus, ~3/4 mile apart: $ ~/nfsSpeedTest -s 5g -y Write test (dd): 49.123 MB/s 392.988 mbps 104.227 seconds That's writing 5*1024^3 bytes of data. If I run the same test but over CIFS I'll get about half the write speed (~25MB/s).
