      Hi Guys

      We here at St. Luke’s Houston are having our CPU usage between 50 – 60%.

      The specs of our Engine are:

      Model: 7026 – M80

      6 CPU’s each 500 Mhz

      14GB RAM

      Paging Space: 6GB

      OS: AIX 5.1 Level 7

      We have 186 real time interfaces right now with around 1 million transactions going through in a month.

      Can anyone suggest if we can fine tune anything just to reduce the CPU usage on the server.

      Thanks

      Amit

          What command are you using to deduce that your usage is in that range?

          BTW, your swap space looks low, probably unrelated. What does lsps -a show?

          I vaguely recall that mem usage in AIX is misleading in that it includes memory buffering held in reserve by the O/S, and not actually in use by the application.

          😎
