[CentOS-virt] BAD disk I/O performance

Hi,

well quickly reading this thread I didn't see anyone
mentioning the I/O scheduler which is the component
with the highest performance impact.

you might want to check you are useing "deadline"
i/o scheduler.

extensive documentation on how to achieve this is
found on the web.
