Re: [Xen-devel] question about disk performance in domU
Adam,
I don't know much about how hdparm really works. Are you suggesting dom0's file buffer cache should
be flushed by default every time because hdparm calls an ioctl to flush? If it is not the case, how
does the data used by hdparm in domU get into the dom0's file buffer cache in the 1st run?
Thanks.

Renato and Tim,
Thank you for your replies.
Is there anyway to flush the dom0 file buffer before running hdparm on domU
each time?
hdparm calls an ioctl to flush it. Maybe that should be passed thru.
