It's only a suggestion and open to adjustment as murali969 sees fit, also hence why (s)he should create several paging spaces to meet the needs, so they are flexible. The real issue is whatever is using all that real memory.
I haven't got anything that big available to me because we do everything on the super cheap for hardware and pay the price in performance and upgrades later.

Hi,
I have paging size 2048M showed from topas and 10240M showed from "lsps -a", can anyone tell what is the difference? and how to change the PAGING SIZE (showed in topas) to 8192M?
Can you please tell in detail step?

gethrtime
gethrtime(9F) Kernel Functions for Drivers gethrtime(9F)
NAME
gethrtime - get high resolution time
SYNOPSIS
#include <sys/time.h>
hrtime_t gethrtime(void);
DESCRIPTION
The gethrtime() function returns the current high-resolution real time. Time is expressed as nanoseconds since some arbitrary time in the
past; it is not correlated in any way to the time of day, and thus is not subject to resetting or drifting by way of adjtime(2) or settime-
ofday(3C). The hi-res timer is ideally suited to performance measurement tasks, where cheap, accurate interval timing is required.
RETURN VALUES
gethrtime() always returns the current high-resolution real time. There are no error conditions.
CONTEXT
There are no restrictions on the context from which gethrtime() can be called.
SEE ALSO
proc(1), gettimeofday(3C), settimeofday(3C), attributes(5)
NOTES
Although the units of hi-res time are always the same (nanoseconds), the actual resolution is hardware dependent. Hi-res time is guaranteed
to be monotonic (it does not go backward, it does not periodically wrap) and linear (it does not occasionally speed up or slow down for
adjustment, as the time of day can), but not necessarily unique: two sufficiently proximate calls might return the same value.
The time base used for this function is the same as that for gethrtime(3C). Values returned by both of these functions can be interleaved
for comparison purposes.
