[CentOS] how to optimize CentOS XEN dom0?

[yonatan pingle]

you should have a look at your I/O disk status.

try with iostat -dx 5 to see the disk utilization info over time.
when it comes to slowdown on a virtual environment on a Desktop grade
machine,  i suspect disk I/O latency and bottleneck as a cause.

check that your disk is running at its optimal state.
look at some indicators , such the the I/O utilization averages,
server load averages
hddtemp /dev/sda will check for heating ( under high load it might )

in any case , you still got plenty of ram to spend.
