The server being copied to (i.e. the NFS server that physically hosts the 
NFS exported directory) is Linux 2.6.24.5-smp.  top shows the CPU to be 
rather idle, but the load looks like this:

load average: 1.62, 1.38, 1.28

That is an usually high load for this machine.  Doing NFS copies between 
linux machines doesn't generate nearly as much load, so perhaps NFS on the 
iSeries is different in such a way to cause this high load?  In my 
opinion, even at this load the machine should still be doing better than 
about 1GB per hour.

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 :)
