Apologies, launchpad didn't keep the neatly tab separated column format, but hopefully the script can help others to test.

Attached png of side-by-side comparison of script output.

Only the latency for accessing a single 4K block doesn't seem to differ too much, but for every other mult-block sequential IO read, in terms of latency, bandwidth and IOPS, GVFS is over 10 times slower than CIFS.

While I know fuse mounts (userspace filesystems) will be understandably slower than kernel space mounts, more than 10 times slower is significant and indicates there's inefficiencies / room for improvement.
