I haven't tuned the threshhold, it is left it at 3/4. I ran
the new qemu/vhost/guest, and the results for 1K, 2K and 16K
are below. Note this is a different kernel version from my
earlier test results. So, f.e., BW1 represents 2.6.39-rc2,
the original kernel; while BW2 represents 2.6.37-rc5 (MST's
kernel).

Weird. My kernel is actually 2.6.39-rc2. So which is which?

I cloned git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git

I am not sure what I am missing.
