Indexing Speed using Java Lucene 2.0 and Lucene.NET 2.0
Hello Everyone,
I have created a Index Application using Java lucene 2.0 in java and
Lucene.Net 2.0 in VB.net. Both application have same logic. But when I have
indexed a database with 14000 rows from both application and same machine, I
surprised that Java lucene took (198 Seconds) more than double time from
.net.(87 Seconds). Is there are any specific reason for that.. or any other
thing..
Also have tried with same of Java Lucene 2.2. Its also took same time..(190
Seconds)
Please let me know if any one have got same..
Thanks in advance,
Laxmilal Menaria

Have you checked that both indexed are the same size to make sure they are
really the same? How much memory does the .net version use? Fast indexing
is simple if you have a lot of memory.

Are you using the same index settings? (mergefactor, maxBufferedDocs,
etc)? Are you using StandardAnalyzer (the trunk version should be
many times faster)?
