FTP, FTP/s, NFS, NFSv4 (with full encryption) benchmark comparisons

[ArtF]

Folks
I am working on a business case for NFSv4 and NAS vs FTP for files.
In our current scenario an application writes a file, FTPs or SCPs the
file and then the next application reads the FTPd file. Because of
this the next application can't use the file until it is completely
FTPd. I am thinking that by using NFS I can start the next
application sooner and even though the NFS throughput may be less than
the FTP or SCP the next application would complete sooner because it
starts earlier. Having said all this I am looking for a site that has
side by side comparisons of well tuned FTP/s and well tuned NFSv4
(preferably including encryption). Any one know of a good site for
this. Thanks much.

It seems to me the result with NFS would be the same. You could
start reading before the file was completely transferred with either
NFS or FTP as long as you didn't read faster than it was written.

Otherwise, read the output of tail -f, but you won't get any EOF
signal so you need to know when you are done.
