For those curious, I'd been having a long standing issue where I
couldn't get more than ~50Mb/sec to an underlying RAID6 array.
Using this testing kernel on both the DomU and Dom0, then adding
xen-blkfront.max=128 to the kernel line of the DomU has managed to give
over 100Mb/sec of sustained writes to the same RAID6 - just about
doubling write speed to the array.
If anyone else comes across similar performance bottlenecks, I'd love to
hear if the above helps out...
