| 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.
