I am trying to analyze the performance of an AIX system. I think I may have a disk I/O issue, but I am asking for help to validate or invalidate this assumption. I ran the commands below during a period of peak load.
Please help me to find any performance bottlenecks. Thanks in advance for your help! Let me know if any more information is required since I am new to performance tuning on AIX.

But I don't know which performance parameters of memory need to be collected. Now, I just know very few:
1. page in
2. page out
3. fre
They are all collected by "vmstat" command.
I want to know, except for above... (2 Replies)

Hi,
I would like to hear your thoughts about this. We are running our Data warehouse on DB2 DPF (partition environment) and I have notice that sometimes we hit the Asynchronous-I/O-Processes peak. DB2 relies heavily on Asynchronous I/O so I would believe this has an negative impact.We are... (10 Replies)
Hello,
I encounter some performance issues on my AIX 5.3 server running in a LPAR on a P520. How do I investigate performance issues in AIX. Is there any kind of procedure that takes me to the steps to investigate my server and find the sub systems that is causing the issues?
The performance... (1 Reply)
Hi,
I'm supposed to capture many performance stats on AIX 6 and stuck up with below:
Priority queue
Disk cache hit%
Page out rate
Swap out rate
Memory queue
I see vmstatis helpful for "page out" but not sure how to get the "rate".
Could anyone please let me know how to get these... (4 Replies)
