Subject MMapDirectory or FSDirectory
Date Thu, 05 Feb 2015 09:13:21 GMT
I am doing some performance analysis with lucene. I have 1 million
resources with 1000 attributes.
According to how I index, I will have 1 million documents with 1000 fields.
For me the total data was about 100 GB and while using FSDirectory to store
my indices, index size was almost 6 GB.
I have virtual memory available of almost 8 GB. Is it advised to use
MMapDirectory for increased performance?
Many blogs suggest it doesnt bring out much performance difference.

Best Regards,
Sreedevi S
