No change in the indexing time after increase the merge factor
I performed lucene indexing with 25,000 documents.
We feel that indexing is slow, so I am trying to tune it.
My configuration is as follow:
Machine: Windows XP, 1GB RAM, 3GHz
# of documents: 25,000
App Server: Weblogic 7.0
lucene version: lucene 1.4 final
I ran the indexer with merge factor of 10 and 50. Both times, the total indexing time (lucene time only) is almost the same (27.92 mins for mergefactor=10 and 28.11 mins for mergefactor=50).
>From the lucene mails and lucene related articles I read, I thought increasing merge factor will imporve the performance of indexing. Am I wrong?

All Lucene articles that I know of were written before
IndexWriter.minMergeDocs was added. Check IndexWriter javadoc for more
info, but this is another field you can tune.
