I am getting very slow io speeds. The disk rate is horrible. Is there a setting that needs to be changed or does Xen just have a slow disk rate? My other question is could I have a poor network connection. When I am copying a file across the network on my 1g nic, that should only take seconds, is taking 8mins. I need some help.

Is this from an HVM guest (e.g., Windows)? -- Keir On 9/1/07 12:04 am, "James Rivera" <jrivera@axacore.com> wrote:> I am getting very slow io speeds. The disk rate is horrible.

And can you post the output of ''dmesg'' from dom0? (usually something like this means that you''re not using DMA for disk transfers, perhaps because your chipset wasn''t correctly detected).>My other question is could I have a poor network connection.

Are you using paravirtualized (PV) or hardware-virtualized (HVM) guests? For HVM guests the networking performance can be poor unless you install the paravirtualizated networking drivers... cheers, S. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Hi, talking about paravirtualizazed networking drivers, are windows drivers now available ? Thank you for your answer.
