[Xen-users] Poor hard disk performance on xen-3/dom0

["Woon Wai Keen @ doubleukay.com" <doubleukay@xxxxxxxxxxxxxx>]

On a vanilla 2.6.12 kernel, I get:
  60MB/s for hdparm -t /dev/sd[a|b] (on an Intel ICH7 SATA controller).
  30MB/s for hdparm -t /dev/hda (Intel ICH7)

On the xen dom0 kernel, I get 20MB/s for all three devices. Xen is 
compiled with the following:
xen_changeset          : Fri Dec  9 11:05:06 2005 +0000 8311:53cff3f88e45
cc_compiler            : gcc version 3.3.5 (Debian 1:3.3.5-13)

Does anyone else face similar problems?
