Commodity disks and NICs are set to make order-of-magnitude increases in performance in the near future. As this happens, the limitations and overhead of virtualising these devices becomes increasingly dominant.

This presentation will discuss the areas of network and storage I/O performance in which the Xen Project hypervisor is weakest. In each area,
* reasons will be suggested for why performance is poor;
* ideas to improve performance will be surveyed (including existing prototypes and future development work); and
* measurements for prototypes that exist will be presented.
