AIX

I searched your first post, ( but its friday so forgive if I zapped...) looking anyware for the 3 servers configurations and find nothing...
Saying they are 3 servers running AIX 6.1 only means to us they have same OS ... they can be quite different in size, resource, proc speed etc... and they can also be on different networks...
We could even imagine 2 are LPARS on the same physical machine ( doing nothing...) and the 3rd an LPAR on a periodically hard working machine...
...
Last but not least, some apps can be running periodically - not using crontabs haha
I think of something like ControlM or even TSM since you are on AIX and chaces are the backup are done by Tivoli...
my 2 cents in addition to Bakunin's
With what you given to us so far it can just be free speculation, you need to gather far more information to be able to start any serious interpolation

All the best

hello vbe,
thank you for your post.
as per your request here you can find some more information about the servers:

Code:

server1 -> lcpu=18 mem=71680MB  Page Space    Size 
                                                            paging01     10224MB    
                                                            paging00     10224MB 
server2 -> lcpu=24 mem=51200MB   Page Space     Size 
                                                             paging01      10224MB   
                                                             paging00      10224MB  
server3 -> lcpu=6 mem=8192MB    Page Space    Size 
                                                          paging01     5048MB   
                                                          paging00     5048MB

Note also that another difference between the 3 servers is that the first 2 act as physical machines while server3 is virtual (vio in the middle)
Also about the comment for the backup, there is no backup running during the times that i get the info, Tivoli is disabled as another backup application is used for backups.

I hope this helps more. If you need additional info please feel free to ask.

There's your problemsss
The slow one is tiny (little cpu or memory) and virtualised... which may or may not be a factor (probably is ;0)
HTH

so you think it is a matter of resources?
if i can add more cpu and memory it will improve the server's behavior?

omonoiatis9, nobody is able to answer that. dukessd has voiced a conjecture (read: educated guess) and maybe he is right, maybe not. As long as you do not publish any data (like the one i have asked for a week ago) nobody will be able to really help you. This is not because dukessd (or i, for that matter) are unable or unwilling to help you, but because we do not know your systems and there are literally hundreds of possible causes.

dukessd himself has called what he said a guess - a good one and certainly based on his considerable experience, but a guess nevertheless. The situation is like you calling a doctor via telephone and asking him: "my left side hurts, tell me what it is."

Show us some data, then we can (maybe) tell you what the problem is. But so far you have only told us some generalities and therefore you get only generalities back.

Sorry, but that's the way it is.

I hope this helps.

hello bakunin,
what data are you referring to? cause i ask if you want any more info then you can tell me exactly what you want and i will give it to you.
if you are referring to the vmstat reports, i attached 2 reports in order to compare.
note that file vmstat_report_rea.txt refers to server3 and file vmstat_report_zeus.txt refers to server1.
if you need more data please be specific in what you need.

thank you.
