Subject Re: Improving Indexing Performance
Date Mon, 08 Dec 2008 09:08:55 GMT

Hi buFka,

take a look to
http://wiki.apache.org/lucene-java/ImproveIndexingSpeed
e.g. your example does not set mergeFactor or RAMBufferSizeMB

I also like the last tip: "Run a Java profiler"
Because in my case, the leak of performance vanished after I switched from
jdom to saxon. 
(we are indexing xml-Files not database tables)

Best regards
  Karsten
