I suspect buf is okay since you're not using any swap -- why shouldn't an OS use free memory as buffer, as long as it's willing to give it up when needed?
Dear Sir,
I have few questions,
1. i already paste the output of top in my thread.
2. how to check on AIX that i/o is taking load
3. how to clean buffer, is there any command that can fix buffer and memory.
Many thanks.

SYSMON(8) System Manager's Manual SYSMON(8)
NAME
sysmon, stats - display graphs of system activity
SYNOPSIS
sysmon [ machine [ -option ] ]
stats [ -option ]
DESCRIPTION
Sysmon displays a rolling graph of various statistics collected by the operating system. The statistics may be from a remote machine. A
sample value is taken once per second. The number in the top left corner of the graph gives the peak value for the duration of the graph.
Lines across the graph represent 75%, 50%, and 25% of the peak value. Clicking a mouse button anywhere in the window cycles through the
list of parameters to monitor; an option letter sets the initial choice. The option letters and parameters are:
[m] mem
total pages of active memory. The memory is displayed as a fraction of the machine's total memory.
[e] ether
number of packets sent and received per second.
[w] swap
number of valid pages on the swap device. The swap is displayed as a fraction of the number of swap pages configured by the
machine.
[c] contxt
number of process context switches per second.
[i] intr
number of interrupts per second.
[f] fault
number of memory faults per second.
[t] tlbmiss
number of translation look-aside buffer misses per second.
[p] tlbpurge
number of translation lookaside buffer flushes per second.
[l] load
system load average. The load is computed as a running average of the number of processes ready to run multiplied by 1000 to give
some precision.
The stats program is invoked by sysmon to display the graph.
FILES
/net/*/[0-n]/stats
#c/sysstat
SOURCE

BUGS
Some machines do not have TLB hardware.
