Currently we are running a VM CentOS on our server via VMWare. I am encountering sluggish performance overtime. On intial creation of the server the speed is extreme but, over time it becomes unbareably slow.
I am a bit confused because we arent using any swap and our load is not terrible.
Here is my top output:
top - 15:38:49 up 1:10, 13 users, load average: 6.94, 6.92, 6.31 Tasks: 165 total, 7 running, 158 sleeping, 0 stopped, 0 zombie Cpu(s): 50.0%us, 50.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 16189104k total, 14704772k used, 1484332k free, 61140k buffers Swap: 4095992k total, 0k used, 4095992k free, 1201532k cached
The top CPU intensive item is

I am sure it is something silly that I am missing but, at this point it takes 20 seconds to SU to another user.
