Any unix server (not just AIX...) can slow down for many reasons. You dont give much clues....
So let me give you some
High load and especially high memory usage -> you are swapping crazy...
To find out :
Code:
lsps -a

commands you could use?
nmon, topas, netstat, iostat vmstat, sar...

To be more precise we would need to know a bit more (OS version, how much RAM and swap, what is running, disks on SAN? etc...)

Performance can slow down for one of several reasons.

CPU or Memory is used up. Or I/O is very high (disk or network). Finally it could be a change in the application which makes it behave poorly.

If you want specific help then we need to know more detail.

NMON and/or topas is good for getting a view on what the server is doing quickly in realtime.
