[Xen-devel] IDE drives

[David Becker <becker@xxxxxxxxxxx>]

I'm seeing quite slow IDE write performance on Xenolinux-1.2 
Native linux writes at 30MB/s to an ext2 fs, and Xenolinux DOM0 gets
about 2MB/s (this is not a virtual disk extent).   hdparm doesn't work
under xenolinux, but that is only part of the problem.  Native linux
writes at 6MB/s without any hdparm tuning.

The SCSI hosts seem fine.  native linux writes to scsi at 36MB/s and
xen at 28MB/s.

Is the IDE speed about what I should expect for xen-1.2 or did I screw
up my configuration?
