hi. 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 performance? maybe adding a phisical drive to the domU? thanks and regards. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
iostat or vmstat can provide i/o wait information. Paras.
