You guys use a AS400 Mainframe as a POS (Point Of Sale)???
Man, talk about overkill.

I would think it wiser, to install an XML application on the 
computers, and that all the intermediate data would be stored inside 
Mysql.

And that the Mysql database, via an EDI(Electronic Data Interface), 
would "talk" with the AS400 system.

I mean AS400 is more an ERP system than it is a POS.

In short I would reconsider using a fullblown ERP as a POS. There 
are better systems for POS.

As far as your question is concerned, check the AS400 Manual in the 
appendixes there is a section for Performance Tuning, and make sure 
the server running CUPS is a fast one. Also do traceroutes to figure 
if a gateway is slowing things down, or other things.

Another way of telling where bottlenecks are is installing Nagios 
(Nagios.org) and use the pinging feature to see which systems are 
slow in reacting. (You can do it without Nagios ofcourse, but with 
it you got a nice monitoring system with it. ;-)
