Some people claimed rx sucks.  Some even posted data.  However, some
experiments we ran here suggested that the problem was _not_ rx.  We
managed to move some significant quantities of data around at reasonable
speeds using rx.  I'm pretty sure we were also able to see performance
problems on vol-dump directly to local disk.

The vos dump performance issue does not appear to have a simple answer.
I'm not at all convinced that rx has serious performance problems.
