I've done some performance tests recently with Xapian 1.0.0, in which 
XAPIAN_FLUSH_THRESHOLD very definitely had an effect.  10 million is a 
very large value, though: unless your documents are very small, or you 
have a very very large amount of memory, you might be getting slow 
indexing due to running out of main memory and forcing your index 
process to use swap...
