: Thanks!  But remember many Lucene apps won't see these speedups since I've

: think for many Lucene apps these are a sizable part of time spend indexing.

true, but as long as the changes you are making has no impact on the
tokenization/docbuilding times, that shouldn't be a factor -- that should
be consiered a "cosntant time" adjunct to the code you are varying ...
people with expensive analysis may not see any significant increases, but
that's their own problem -- people concerned about performance will
already have that as fast as they can get it, and now the internals of
document adding will get faster as well.
