Excellent news!

That is a surprising difference, since as you no doubt know, "ZOOM
indexing" is merely the use of ZOOM to pass the records to Zebra for
indexing.  I flatly refuse to believe that the communication layer is
responsible for a slow-down by a factor of 16, so something else is
going on here.  My best guess is that "zebraidx update" is making use
of caching mechanisms that ZOOM's update requests are not benefiting
from.  There may be a way to have ZOOM request that caching: Adam will
be able to tell us.
