Re: [Xen-devel] poor I/O performance on domU

Is /dev/hda what dom0 is mounted from? If so, can you try the test
again with a neutral partition (one that neither has mounted)?
yes, dom0 filesystems are on partitions located on hda.
I've tried exporting /dev/hda7 (not used neither mounted from dom0) as
sdb7 and I can get about 12.3 MB/s. From dom0 I get about 14.8 MB/s.
Tested by `time dd if=/dev/{s|h}hda7 of=/dev/null bs=1M`, about 4.5GB of
data.
