Joe,

In my case it did not seem to matter whether they were on the same machine
or not.  I got more consistent results on the same machine, but the best
performance in this case came running the servlet off of the iSeries. This
was about a year ago and the difference was around 4-5 times better with
the tunneling approach.  I do believe this difference was exaggerated due
to a data queue wait problem is likely to have been fixed. It is always best
to try these things out in your own environment; I was just curious to see if 
you
had experienced this and wanted to find out if you knew of fixes or workaround.

David, I suspect that pure sockets is still the fastest way to go for remote
clients.  It's extra work, but hard to beat from an overhead standpoint.
Personally, I like the data queue approach because most of my work uses
servlets and the database tier and the presentation tier reside on the same
machine, whihc may negate some of the benefits of the socket approach.

I'd say that the best way to find out is simply to run some performance
tests.
