Subject RE: Making lucene indexing multi threaded
Date Mon, 27 Oct 2014 15:47:07 GMT
Hi Fuad,

Thanks for your suggestions and quick response. I am using a single-threaded
indexing way to add docs. I will try the multiple-threaded indexing to see
if my issue will be resolved.

This issue only exists after I upgraded lucene version from 2.4.1(with Java
1.6) to 4.8.1(with Java 1.7). I don't have this problem in old lucene

The indexing speed is fast when i start the application, which only takes 3
mins indexing. But after my application running for a while(a day, etc), 
once i send a JMX call to my application to reindex docs, the indexing speed
will slow down and take 22 mins.

Did you have any similar experience like the above before?

Thank you,
