i was migrated an old woody samba server to a new lenny samba
virtualized server.

That server is a PDC with random profiles and file server.

Some users are reporting me bad performance in the app shared (all
developed on MS-ACCESS).  the memory and cpu reports in the domU show
all fine, but i have some doubts in the disk performance.  The dom0 is
a Dell PowerEdge T610 (2 cpu Intel Xeon, 8GB RAM)

the domU is a vserver created using the xen-create-image options, to
create a "hard disk" on ext3 file system.

the old server was a poweredge 2600 with scsi disks.

how can i confirm if the domU server have really a bad disk perfomance
(compared with the old server) and how can i optimize that disk

maybe adding a phisical drive to the domU?

thanks and regards.
