I always start with topas, it provides a single screen overview of the system. You can then drill down further using the commands and information that Sankret has provided in his post.
I'd also recommend collecting nmon data (https://en.wikipedia.org/wiki/Nmon), either via the more traditional csv route then you can utilise the nmon analyser to analyse this data. Or implement the newer nimon/njmon to feed data to a time series database for presentation in Grafana - https://nmon.sourceforge.io/pmwiki.php?n=Site.Njmon

Subject: AIX performance slowness check
Hi Team,
How can we do the performance/slowness check of AIX LPAR? If someone facing slowness issue what parameter and command we can look into it. Do we have any general documents/commands to check in terms of memory/CPU/disk/network/error? I know there is no definitive answer but wanted to know if some basic commands we can start from and from where we can move further. Thank you in advance.
