Re: NFS vs. SFTP which one faster?
Thanks Rick again.
Yes, currently, this data transfer job spends around 3 or more hours per day. It was set in crontab job and started at 4:00 a.m., it looks like a little bit long, so that's the resson why I asked NFS vs. SFTP which one is faster.
Queston for Rick, could you provide me more details about IPSEC, like how to set it and how to get this ... is it network side or HP-UX server side? "running NFS over IPSEC..."
thanks.

Re: NFS vs. SFTP which one faster?
I am afraid I do not know the specifics of enabling IPSEC - one or more of the UX or networking manuals at https://support.hpe.com/hpesc/public/home should discuss it. I take it you are making these transfers over a network not entirely under your control?

o Kerberos Authentication
o Send & Receive Data Checksums
o End-to-end Data Encryption and Checksums
Of course adding any kind of security will "impact" performance (Hi Rick - he hates that. ;)
However, if you're running this stuff across a 100MB link you're probably not too overly concerned about performance anyway.

Re: NFS vs. SFTP which one faster?
Wisdom Teeth are impacted, people are affected by the effects of events.
Now, enabling security - especially encryption - will _affect_ :) service demand (quantity of CPU consumed per unit of work - something netperf will report for its tests if you ask it to), and a sufficiently large increase in service demand may _affect_ throughput.
How much is, of course, one of those (in)famous "it depends" sorts of questions.

Re: NFS vs. SFTP which one faster?
Those two HP-UX servers are running 11i v1 (although we do have v2 and v3 OS installation CD/DVD for so many years, but so far my boss no upgrade plan), I haven't heard Secure NFS in v1, It look like it using SSH protocol.
In this case, I think transfer speed is more important than security.

Re: NFS vs. SFTP which one faster?
If I _really_ wanted to know, rather than
asking people who know less than enough about
my whole environment, I'd run a test. (I
know that it's a radical concept, but I'm odd
that way.)

If your CPUs are faster than your network,
adding compression (gzip, bzip2, ...) to that
pipeline might help. Full command examples
abound in this forum.

Hmmm. I'd say that people are affected by
events, not, generally, by the effects of
events. (There may be a limit to the amount
of wisdom which can be crammed into one pithy
remark.)
> American Heritage sayeth thusly -
Sadly, even good dictionaries tend to include
defective usage when it becomes sufficiently
common. Diluting "impact" to mean no more
than "affect" (or "effect") destroys much of
its value. (Dare I say, its _impact_?) One
(perhaps the only) benefit of using "impact"
everywhere is that semi-literates who haven't
mastered the difference between "affect" and
"effect" seem to be able to cope with
"impact" and "impact".
