Summary: CentOS is not getting optimal performance in a virtualized
environment and on slow cpus
but I am not sure I understand the current best practice. Your thoughts
would be appreciated.
Options as I see them:
1. Run kernel-vm-2.6.18-53.1.4.el5 with clocksource=pit until the
excellent CentOS team builds the latest kernel into a VM kernel (This is
working for me now).
2. Run kernel-2.6.18-53.1.6.el5 with divider and hope the clock does
not go fast (I have not tried this).
