This should be much better. I found that QEMU would issue FLUSH to
sheepdog even no object cache enabled. This will hurt write performance
I will send a patch for QEMU to eliminate unnecessary FLUSH request
without object cache enabled or start up QEMU VM as 'cache=directsync |
none | off' even with object cache enabled on sheep daemon side.
All these fixes might be included in next stable QEMU release.
