AIX performance issue

Hi Guys,

This is the situation I am in. Provide your views and input where should I start?

I have one P7 test server and a p520 production server. the job is taking pretty long on the P7 test server when compared to the P5 production server. below is the full detail.

Informix transaction activity and archive processing are taking
noticeably longer on the Power7 8233-E8B 12way/3.3GHz processor with
128GB of memory running AIX Version 6.1. The Informix LPAR in
question has 3 cores and 16GB of memory assigned. The system has been
fully configured to be virtualized with 3-4 LPARs and 2 x VIOS LPARS
supporting all I/O. The SAN storage consists of a 4Gbps Fibre
Channel SAN with an IBM SAN Volume Controller supporting an IBM
nSeries N5600 and an n6040 plus a fully populated DS4800. This is
the first time the customer has had any LPAR environments in their
data center. The systems were initially configured by 2 x IBM
Advanced Technical Support specialists due to the complexity of the
environment.

The current Informix environment and ATM processing application is
running on an IBM 8203-E4A model 520 with 4 x 4.2GHz processors, 8GB
of memory, and Version 5.3 of AIX, attached via fibre Channel to a
shared EMC CX3-40C Clariion storage unit. On the model 520, the
archive process is taking 25 minutes to archive 96GB of data while
still supporting user activity. But on the model 750 it is taking
around 45 minutes to complete. The archive process is a single
threaded process and, we believe, is not being able to take full
advantage of the additional processors and advanced architectural
design of the Power 7. This could be due to lack of proper tuning of
the OS or other undiscovered factors. The Informix environment and
the ATM application code are running the 32bit version of their code
on the model 520. But on the model 750, the Informix software is
running the 64bit version but the software vendor's application is
still running the 32bit version of the application.

Thank you.

NAME
nwpjvm - Move print job to Unix queue SYNOPSIS
nwpjmv [ -S server ] [ -h ] [ -U user name ] [ -P password | -n ] [ -C ] [ -q queue name ] [ -c command ] [ -j job number ] [ -d ] DESCRIPTION
nwpjmv is a program that connects to print queues on NetWare servers and moves a designated print job to a Unix queue. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the print server name at the server. -P password password is the password to use for the print server at the server. If neither -n nor -P are given, and the user has no open connection to the server, pserver prompts for a password. -n -n should be given if the print server does not require a password. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. -q queue name queue name is the name of the print queue you want to service. -c command nwpjmv removes the designated job from the Novell queue and feeds the job file to stdin. command is the printing command that is exe- cuted for each job. The default command is 'lpr'. You can insert several flags into the command, preceded by %. These are replaced with values retrieved from the queue structure for the print job. %u: This field will be replaced by the name of the user who posted this print job. %d: This field will be replaced by the job description field of this print job. -j job number This designates the ID number of the print job to be moved. -d causes extra error messages to be logged.
