server performance..
Hi,
would like to know the server status from the following 'top' out put. Because, the application is giving a bad performance. would like to know whether the load is within the acceptable limit. Murali... Code:

Hi,
I thought load should always be less than 0.3 for the better performance. And one more thing is, CPU utilization is 99% for the processes ndmcmgr & cdstatm. wudn't this impact the response of the other processes... Murali

I don't know where you got that .3 but it's way too low. You have double digit idle times on every cpu. You do have two processes that spend 98% of their time in the cpu. The kernel knows this and has given them a nasty priority. They only run when nothing else wants to. Since you have double digit idle times on each of your four cpu's, yes they run a lot.
HP has a product called glance or maybe it's glance-plus now. It looks like you can download a trial version here. Try it. It will tell where your bottlenecks are.
