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.

swapoff
SWAPON(2) BSD System Calls Manual SWAPON(2)
NAME
swapon, swapoff -- control devices for interleaved paging/swapping
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
int
swapon(const char *special);
int
swapoff(const char *special);
DESCRIPTION
The swapon() system call makes the block device special available to the system for allocation for paging and swapping. The names of poten-
tially available devices are known to the system and defined at system configuration time. The size of the swap area on special is calcu-
lated at the time the device is first made available for swapping.
The swapoff() system call disables paging and swapping on the given device. All associated swap metadata are deallocated, and the device is
made available for other purposes.
RETURN VALUES
If an error has occurred, a value of -1 is returned and errno is set to indicate the error.
ERRORS
Both swapon() and swapoff() can fail if:
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
[ENOENT] The named device does not exist.
[EACCES] Search permission is denied for a component of the path prefix.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[EPERM] The caller is not the super-user.
[EFAULT] The special argument points outside the process's allocated address space.
Additionally, swapon() can fail for the following reasons:
[EINVAL] The system has reached the boot-time limit on the number of swap devices, vm.nswapdev.
[ENOTBLK] The special argument is not a block device.
[EBUSY] The device specified by special has already been made available for swapping
[ENXIO] The major device number of special is out of range (this indicates no device driver exists for the associated hardware).
[EIO] An I/O error occurred while opening the swap device.
Lastly, swapoff() can fail if:
[EINVAL] The system is not currently swapping to special.
[ENOMEM] Not enough virtual memory is available to safely disable paging and swapping to the given device.

HISTORY
The swapon() system call appeared in 4.0BSD. The swapoff() system call appeared in FreeBSD 5.0.
