I have been performing some tests concerning the scalability of sheepdog. I've noticed that the throughput of write operations does not increase beyond 6~7 MB/s, in a two-nodes cluster. The workload is being generated to a VM running on a sheepdog VDI. Do you have any information about the maximum synchronization throughput (in MB/s) obtained using sheepdog? In the KVM Forum slides, there is a bar plot showing around 15 MB/s for the throughput, but I think this is the total rate, considering both read and write operations performed by the "dbench" benchmark, am I right?
