Besides priority, pay attention to nice/renice. That basically skews/modifies the priority. Negative nice means priority advantage, positive means disadvantage. These will be important though only if your box is pounded by CPU, I/O or memory.
If something is very slow, I'd check out if you have enough RAM. If the box starts to swap, that kills the performance. Another thing is the I/O subsystem, how it works, drivers, file systems, etc, how is it tuned. You can try SAR or other toolset. http://www.thegeekstuff.com/2011/12/linux-performance-monitoring-tools/ Csaba ________________________________________ From: [email protected] [[email protected]] on behalf of Howard White [[email protected]] Sent: Tuesday, November 20, 2012 11:45 AM To: [email protected] Subject: Re: [nlug] the continuing saga of the reluctant systems administrator On 11/20/2012 01:37 PM, Sabuj Pattanayek wrote: > ps -axl | grep cups > > 5th column, but I don't think that's necessarily your problem.

That was sorta the genesis of this project. We needed to upgrade the OS to support the latest version of Informix. Went from RHEL 5.2 to CentOS 6.3. > Any chance of using KVM to do the virtualization? Yeah, two chances: slim and none. Boss won't hear of using anything but esxi.
