Hi Uwe,
Could you tell what Analyzer do you use when you marked so big indexing
speedup?
If you use StandardAnalyzer (that uses StandardTokenizer) may be the
reason is in it. You can see the pre last report in the thread "Indexing
Speed: 2.3 vs 2.2 (real world numbers)". According to the reporter Jake
Mannix this is because now StandardTokenizer uses StandardTokenizerImpl
that now is generated by JFlex instead of JavaCC.
I am asking because I noticed a great speedup in adding documents to
index in our system. We have time control on this in the debug mode. NOW
THEY ARE ADDED 5 TIMES FASTER!!!
But in the same time the total process of indexing in our case has
improvement of about 8%. As our system is very big and complex I am
wondering if really the whole process of indexing is reduces so
remarkably and our system causes this slowdown or may be Lucene does
some optimizations on the index, merges or something else and this is
the reason the total process of indexing to be not so reasonably faster.
Best Regards,
Ivan

This week I switched the lucene library version on one customer system.
The indexing speed went down from 46m32s to 16m20s for the complete task
including optimisation. Great Job!
We index product catalogs from several suppliers, in this case around
56.000 product groups and 360.000 products including descriptions were
indexed.
Regards
Uwe
