Poor Performance

Cristina Sunshine — Tue, 16 Jan 2007 07:31:37 GMT

Hello All,

HP Server rp3440
1 CPU
6GB Memory
Progress Databases

We are currently having a serious performance issue here.
I am a DBA and I have checked all the Database parameters and they are okay.
I am very concerned about the load average of the TOP Output, the value is very high.

I would like to know if High Load Average could impact on the performance ??

Any commands to get statistics information will be greatly appreciated.

Kind Regards,

Cris

Cristina!

For memory issues, check with dmesg, swapinfo -tam, for disks issues, check with sar -d, same for the cpu, algo glance is a great tool for performance issues.

Regards,

Jaime.

Shalom,

By itself a high load average only indicates a lot of processes are waiting for cpu. It is not by itself the indication of a performance problem.

A good set of background free tools for getting a handle on performance problems.

There's not very much you can do until you identify the processes that are consuming the resources. A high load average is normal if you have dozens of processes all trying to run at the same time (typical for a busy database) and just one CPU. You have a lot of memory which is good, but with just one CPU, you'll have to limit the number of users or simultaneous DB access points. The rp3440 is a good little machine but without a second processor (max allowed for this model), it will always be single-threaded. That means that everything from kernel to drivers to Progress code to filesystem access will all go through the one processor. The load average (from top or uptime) is a rough indication of how many processors you really need. A load of 1.0 is normal for your machine, 2.0 is busy and anything more means the system will be very slow.

Also check syslog.log for any error messages.

HEllo Everyone!!

Thanks a lot for everyone who has responsed.

Which file in HP-UX would show me how many CPUs and Memory I have?

I ran sar -d and here is the output:

Where should I look to see whether we have a disk or a CPU bottleneck?

Many Thanks!!!
Kind Regards,

This is a relatively new system right?
Was it sized correctly, or perhaps undersized?
Do you have something to compare against, that is.. was this an upgrade from a prior PA-risc solution perhaps?

You write 1 CPU. That's the PA 8900 right? 800 Mhz or 1 Ghz?
1 core enabled only?
Maybe it is time to activate a second core or even add a second cpu, as there is room to grow in the box.

Personnaly I do not like single core servers ever. 2 cores seems a much better deal to me!

Just eyeballing what you shown sofar, I notice a good amount of memory and disks which may very well need a whole cpu core to drive.

Hope this help some,
