Same settings on Centos 5.3 and 5.8 but difference in Oracle

Postby Rick_Smith » 2012/07/18 13:30:16

Hi,

We have two systems running CentOS5.3 and 5.8 respectively, the one with CentOS5.3 has better performance than the one with CentOS5.8.

I have verified that the kernel parameters in /etc/sysctl.conf and /etc/security/limits.conf are identical.

The machines are identical with respect to CPU and memory.

Can someone help guide me as to where I should look next?

Thanks in advance......

Don't know if this makes a difference but they are both VM's on VMware
