I am interested to see the performance for read and writes separately. Aggregated will probably be much influenced by the read performance.
Interesting the last figures, seems quiet a significant performance gain using the QEMU-GlusterFS.
See if you can get the results for read and writes separately.

Ok, here are the aggregated bandwidth numbers from a quick FIO (4 seq writes using libaio) write test:
QEMU-GlusterFS native: 150635KB/s
QEMU-GlusterFS FUSE: 43028KB/s
So as you can see, native is much better than FUSE, but still doesn't match the base numbers. When I say base, it means that the guest is run directly from glusterfs brick (w/o gluster FUSE mount or using QEMU-GlusterFS native driver).

FIO at the moment. Plan to include more benchmark numbers in future.
Any help here would be appreciated :)

No, QEMU-GlusterFS native numbers are way better than FUSE. Let me quote the numbers from the URL I gave earlier:
QEMU-GlusterFS native: 53609KB/s
QEMU-GlusterFS FUSE: 29392KB/s
