volserver doesn't give you a lot of RX knobs to fiddle with,
unfortunately (assuming you're "vos move"ing a bunch of volumes).

However, you may get different results depending on the version you're
using. What version are the fileservers in question running? You also
_may_ get some improvement by using RX jumbograms (specify -jumbo for
the volservers) if the network you're going over can handle them, but
probably not to the degree that you're hoping for.

Or you actually may get improvement by disable jumbograms, if they're
enabled by default in the version you're running (specify -nojumbo).
