I agree with Ken, you need to figure out what is eating your lunch, as they say. You have several programs such as top, and system monitor that can give you some high level look into what is going on. Also, how much memory is on the machines and what type of cpus are installed. If you can provide some info either from top or system monitor that may help in providing some additional assistance also. jim On Mon, Oct 4, 2010 at 2:26 PM, Kenneth Kirchner <ken@xxxxxxxxxxxxx> wrote: > I would recommend installing some kind of performance monitoring software > like Nagios or just SNMPd and Cacti.
