Your system seems a bit sluggish too, doesn't it?
I'm getting 55-60 MB/sec for buffered reads and 1600 for cached.
AFAIK, standard modern ATA disks should give you around 50 MB/sec read speed...
Yup. However i don't know what is actually wrong here. This is a standard seagate 20GB and the host kernel is the stock xen
3.0 stable kernel.
