Hi, I notice that domain 0 gives bad performance with disk I/O. Domain 0 was given about 55MB RAM. With the same configuration, Linux on raw hardware gives far better performance. While a raw Linux OS gives a disk read throughput of around 20MB/sec (without any caching effects), dom0 (using the Xen.2.0.4 kernel with linux kernel 2.6.10) gives only about 2-3MB/sec throughput. Any pointers to the reasons for this difference will be greatly helpful. Thanks, pradheep. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
