Subject ParallelMultiSearcher vs. MultiSearcher
Date Sat, 06 Mar 2004 16:20:17 GMT
Under what conditions would a ParallelMultiSearcher be faster than a 
MultiSearcher?  In my brief tests (26 partitioned indexes, all running 
local), ParallelMultiSearcher is a factor of 2 or 3 times slower (we're 
still talking 20ms versus 60ms though).  I'm searching a partitioned 
set of indexes of around 40,000 documents through a RemoteSearchable.

I'm just curious under what circumstances you'd use the new 
ParallelMultiSearcher instead of a MultiSearcher?  I saw mention of 
multiple hard disk drives being a reason.  Has anyone used it in this 
environment and shown that there was a benefit?
