Run omething like "iostat -mx 3" on the virtual server. If disk
utilization is often close to 100%, then you have the culprit.
Sometimes you don't necessarily need to have a dedicated disk. You
have to make sure that it's used optimally. e.g:
- whenever possible, don't use HVM guest. Use PV guests instead.
- use block device (partition, LVM, whole disk) instead of file-backed image
- when you have to use file-backed image, use tap:aio instead of file:/
