AIX 7.1 on Power 750 is very slow with no high memory or process consumption

Hi,

This thread has been posted before on linuxquestions.org, but no answer, maybe because this is unix question and not linux. I'm posting the same thread here, hope I can get an answer from someone in the meantime, I wish I could post of emergency thread but it needs bits which I don't have :

I'm posting this thread because first I'm a newbie on AIX (I've been a Linux Admin for almost 3 years and we have AIX for some project requirements) and second I could not find any useful info on that over the internet.
These servers are handed over to us by the client. We are experiencing slow performance on the console, on login (using Putty or any shell client on windows, the password pops up with a big latency) and on our Application Server (Oracle Weblogic 10.3.6). Here are the output of some of the usual commands :

Code:

-bash-4.2# svmon -G
               size       inuse        free         pin     virtual   mmode
memory     16842752     1459856    15382896     1291104     1392007     Ded

PageSize   PoolSize       inuse        pgsp         pin     virtual

And here is the topas sample output:

I even tried to check the bandwidth with a big file transfer and that looks fine.
Let me know if any other info is needed, actually we are stuck with this issue and we need to find a solution as soon as possible.
