What you need to do is measure all the parts of the process on both machines
and any equipment in between and identify which part is the hold up using
benchmarks and data. Locate the problem with numbers not prejudice.

It may well be the iSeries that is the problem, but with your approach if it
isn't you'll *never* get it fixed.

I'm not sure what kind of attitude you're referring to. The performance of NFS on my iSeries is significantly less than that of my other machines and I posted a question asking how to resolve that. I tried the suggestions offered and posted my suspicions as to the cause. The tests I've done back up my suspicions. I don't know everything, thus I post here. I believe I am following the scientific method: make an observation, form a hypothesis, and do tests to confirm the hypothesis.

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
