Re: system run slow

So far, you've told us that the car is running very slowly but there are no dead bodies in the trunk.

If you post the entire 1st page of top's output that might prove useful; some sar outputs could help; swapinfo; bdf, kmtune (or sysdef) output. A ps -ef could help as well. By far the best tool to use to find your problem is Glance.

It would help to know a little bit about your system as well? Hardware, memory, applications, OS versions AND has the system just started running poorly or has it always been like this.

The more data you provide, the better the help you are likely to receive.
If it ain't broke, I can fix that.

I wonder if the name of the server is "Hearse" ?

Re: system run slow

The first thing I would do is to check the system with GlancePlus:
# gpm

This will list you all processes running, resource usage etc. Determine which option will solve the problem from the outputs. You can also try sar:
# sar 1 10
# man sar

Re: system run slow

Bad performance can be caused by one or several bottlenecks (memory, cpu, disk network, kenel config, application). One question to ask can be what was done to the system prior to the problems starting? Another important question is what kind of performance problems are reported (application only, certain commands/taske, HP-UX commands, etc.)? Then you can start checking with the tools already mentioned. And you should know what values they give on a "normal" system.

Re: system run slow

First I think you must check the highest CPU% usage process from top!
Is your system can't meet the requirment of some applications?(For example, CPU/memory ) If no problem,please use bdf to see if the free diskspace is enough. Other tools you can use: sar,iostat,vmstat,swapinto etc. You can use these free tools or use GlancePlus to check where the bottle-neck is!
