Thanks much for your response....@ Robin, @ Zaxxon...and @Michael
I really appreciate your ideas.......
As per your comments/ideas, i understand that
It is not a problem/bottleneck...If RAM (memory) utilization in AIX goes beyond 99% .
The only issue is when there is a paging activity......lets say....paging space goes above 20% (page in/out)
In my case, i see lot of Memory utilization 99% all the time
but 1% paging space.
no paging activity.
REAL MEMORY --> 24 GB
% comp --> 29
% non comp --> 64
% client --> 64
paging space
1 % used
Please correct me if i am wrong.

dynamic_pager
dynamic_pager(8) BSD System Manager's Manual dynamic_pager(8)
NAME
dynamic_pager -- external storage manager for dynamic pager
SYNOPSIS
dynamic_pager [-F filename] [-S filesize] [-H high-water-trigger] [-L low-water-trigger] [-P priority]
DESCRIPTION
The dynamic_pager daemon manages a pool of external swap files which the kernel uses to support demand paging. This pool is expanded with
new swap files as load on the system increases. It is contracted when the swapping resources are no longer needed. The dynamic_pager daemon
also provides a notification service for those applications which wish to receive notices when the external paging pool expands or contracts.
OPTIONS
-F The base name of the filename to use for the external paging files. By default this is /private/var/vm/swapfile.
-H If there are less than high-water-trigger bytes free in the external paging files, the kernel will signal dynamic_pager to add a new
external paging file.
-L If there are more than low-water-trigger bytes free in the external paging files, the kernel will coalese in-use pages and signal
dynamic_pager to discard an external paging file. Low-water-trigger must be greater than high-water-trigger + filesize.
-P This option is currently unimplemented.
-S The fixed filesize [in bytes] to use for the paging files. By default dynamic_pager uses variable sized paging files, using larger
sized files as paging demands increase. The -S, -H and -L options disable that default and cause dynamic_pager to use a series of
fixed sized external paging files.
FILES
/private/var/vm/swapfile* Default external paging files.
/Library/Preferences/com.apple.virtualMemory.plist Configuration file.
XML PROPERTY LIST KEYS
The following keys can be specified in the configuration file. Please see plist(5) for more information about property list files.
UseEncryptedSwap <boolean>
This optional key activates encrypted swap (aka Secure VM), so that all data is encrypted before being written to a swap file. The default
is on for portable computers and off for other computers.
