Subject No change in the indexing time after increase the merge factor
Date Tue, 20 Jul 2004 15:28:39 GMT
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?
