  • Thread-topic: [Xen-devel] [Patch] Buffer disk I/O requests

Disk I/O of VM is slow compared to native, I/O port access consumes time
significantly, which could be partly improved with buffered I/O.  
The attached patch partly improves the performance of disk I/O through
buffering Disk I/O requests.
