Moving data between servers using NFS mounts and the cp command

Generally speaking is it faster/better to copy data FROM a local filesystem TO an NFS mounted filesystem or is it faster/better to copy data FROM and NFS mounted filesystem TO a local filesystem?
Hey! Who turned out the lights!

I know nothing, but I'd expect little
difference.

Why not run the experiment? I'd trust
reality more than any advice you might get
here.

Re: Moving data between servers using NFS mounts and the cp command

well I suppose it should be the same because we using same network same protocol, the only difference is we only initiating the process from different server.

Its true check for the real input by doing it.

No measureable difference...NFS is simply slow, especially for small files. There is a large amount of traffic needed to find, open and close each file. ftp will be significantly faster. If this is a regular task, you will find rsync even faster for files that don't change a lot.
