What you are seeing is most likely file system caching. Solaris considers unused memory a waste, so it parks (caches) data read from files or written to files in memory because it improves performance. The kernel will release file caches anytime there is a need for more memory.

Anyone know how to fetch the system performance information by the function except the system command? These information includes CPU load,memory usage,network load,disk capacity,etc. (5 Replies)
I have received an order from upper level manager to "verify system information via Perform/predict'. They asks me to *predict* the system performance. How can I do it as a system admin without the help of application admins and DBAs?

vxfs_ifree_timelag - VxFS inode free time lag (specifies the minimum time to be spent on a freelist)
SYNOPSIS VALUE
Specify an integer value.
Minimum
None
Maximum
None
Default
0
DESCRIPTION
In VxFS, the unused inodes are put on a freelist. The memory space for this unused inode is freed if it stays on the freelist for a speci-
fied amount of time. The tunable specifies the minimum amount of time should spend on a freelist before its memory space is freed. The time
is specified in seconds.
is a dynamic tunable. Any changes to take effect immediately.
EXAMPLES
Change the value of to 2400 seconds:
WARNING
Incorrect tuning of may adversely affect system performance.
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or its meaning may change in the future releases
of HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
