[Xen-users] xvd Device Performance

Hi All,


Has anyone been able to get near native disk performance out of a xvdX device? The xvdX device maps to a LV disk partition.


From the DomU:



Timing cached reads:   22960 MB in  1.98 seconds = 11578.12 MB/sec

Timing buffered disk reads:  152 MB in  3.01 seconds =  50.46 MB/sec


The disk that the xvda links to:



Timing cached reads:   22992 MB in  1.98 seconds = 11600.27 MB/sec

Timing buffered disk reads:  308 MB in  3.01 seconds = 102.20 MB/sec
