AIX 5.3 performance problems
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 issued encountered is that user logging in to the server with telnet encounter hiccups in the screen updates. They use a text based application and sometimes the screen updates do not follow the keyboard input immediately. It can take up to 5 seconds for the screen to update. To be more precise: When they hit F1-F2-F3-F4 it sometimes stays at screen F1 and then after some delay it will step through screens F2, F3 and F4 . At other times the application/system will just quickly step through the screen when the Function keys are pressed.

At first glance I cannot find a related CPU, Disk, memory or network problem but I'm not knowledgable enough to to know for sure.

So is there any performance investigation procedure for AIX?

x11perfcomp

x11perfcomp(1X) 														   x11perfcomp(1X)

NAME

       x11perfcomp - X11 server performance comparison program

SYNOPSIS

       x11perfcomp [-r	| -ro] [-l label_file] files

OPTIONS

       x11perfcomp  accepts  the  options listed below: Specifies that the output should also include relative server performance.  Specifies that
       the output should include only relative server performance.  Specifies a label file to use.

DESCRIPTION

       The x11perfcomp program merges the output of several x11perf(1X) runs into a nice tabular format.  It takes the results in each file, fills
       in  any	missing  test  results if necessary, and for each test shows the objects/second rate of each server. If invoked with the -r or -ro
       options, it shows the relative performance of each server to the first server.

       Normally, x11perfcomp uses the first file specified to determine which specific tests it should report on.  Some (non-DEC  :)  servers  may
       fail  to  perform  all  tests.	In  this case, x11perfcomp automatically substitutes in a rate of 0.0 objects/second. Since the first file
       determines which tests to report on, this file must contain a superset of the tests reported in the  other  files,  else  x11perfcomp  will
       fail.

       You  can provide an explicit list of tests to report on by using the -l switch to specify a file of labels.  You can create a label file by
       using the -label option in x11perf.

X DEFAULTS

       There are no X defaults used by this program.

SEE ALSO

       X(1X), x11perf(1X)

AUTHORS

       Mark Moraes wrote the original scripts to compare servers. Joel McCormack just munged them together a bit.
