It is expected that NFS will be slower than any "normal" file system such as EXT3. Transferring files over the network is the main reason for the additional delay.
I am wondering how NFS can be compared with other file systems. Let us assume the NFS server and the clients are located on the same Gigabit LAN. Also, let us assume we have only 10 clients.
Is there any benchmarks that we can look at? Can we say some like the following?
NFS delay ranges from 150% to 200% when compared to other File systems??
Of course, many factors can affect the delay such as read/write operations on disks and files' sizes. Can we have an approximate measurement of delay difference?
