Question Poor resourece allocation (multi-user system)

All,

I am an intermediate user, and am running SAS on a nice Solaris machine. However, even when top says that no other programs are running, the machine will only give me 5-7% processor power. Is this a configuration problem with SAS or the way the server is configured? Is there any way I can get more resources without bugging the admin? Any help is appreciated.

Thanks,
Ian

Chances are you are I/O bound - meaning that your process is spending most of it's time waiting for disk I/O to complete.

You could be reading/writing temp files, for example.

As Jim says, if your process only gets 5% to 7% of the cpu when no other processes are running, that is all that it wants. It is waiting on something else. Most probably, it is waiting for I/O to complete.

If you are having performance problems, you should work with the system administrator. This is part of their job.

There may not be a magic bullet, If you need faster disks or something, there may not be $ for that. On the other hand, there may be a magic bullet. Sometimes you can do stuff like moving files to less busy disk. So it is worth a try. If nothing else, the sysadmin will be aware of the problem.

Thanks for all your help guys. I'll chat with the sysadmin today.
