Why not do some profiling first.  Maybe it's limited by i/o traffic
rather than cpu cycles.  I don't know how Lupy works but the one time
I messed with full text indexing, the bottleneck was definitely the
random disk accesses needed for every word of each update.  The
solution is to batch the updates.  Sorting is much less seek intensive
than random updates.
