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.

Please edit your initial post with pasting the actual command output. That would make it much readable. There should be properly aligned columns here.

i have 32 G of RAM , please i need if my system is still ok or No?
As you are asking, probably not. You might want to cap ZFS ARC size but that really depends on the applications you are running and their memory footprint.
Your can see "vmstat 1 5" output to determine the system performance.
ZFS will use physical memory as ARC cache unless until it used by application.
When application needs more memory ,ZFS will release the cache automatically.
So you really no need to worry about that.
From the below output,you just need to monitor r,b,w columns and sr column (scan rate).If these values quite more,then your system performance is degraded
hi every body i want to check system performance i usually use glance,top,sar and swapinfo but i confused in something so i need explanation about memory issue
first i want check the memory usage i used glance i found this parameter so i need one shows me the differences between these... (2 Replies)
Dear experts ,
Pls advice for any good Tool to monitor the CPU and performance of AIX the system ..
to keep monitoring to show me the utilization of that system .. (12 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?

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 need to prepare script which will run as background process ever 30 mins to collect the following information
1. Memory usage.
2. CPU usage.
3. Number processors running.
4. System resource (CPU and Memory) used by each process.
5. Number of sessions logged
PLEASE HELP ME OUT FROM THIS

I'm running Solaris 8 on a Sun ULTRA 5(SPARC II CPU, 270 MHz) with 64 Mb of RAM.
The machine is very, very slow even doing normal tasks such as reading mail....... I'm nearly afraid to ask it to do some real work.......
On checking out the machine(which I only received last week from our IT... (1 Reply)
Could someone point me in the correct direction or web link containing instructions for installing the System Performance Tool (aka STP) software on an IBM-AIX version 4.? machine. My client has the software (that came from their original server) on a 3" floppy. Thanks! (1 Reply)
