There is strace analysis in Shyam's comment #10. Please take a look. We can
collect again if needed.

In the meantime, I'd very much like to get a primer on the metadata gluster
maintains on the brick: what, why, and how it figures in the I/O path. If you
can point to a link where this is documented, or post here, or discuss offline,
that would be very useful.
