I use Hibernate Search 3.2.0 with Hibernate 3.5.1 and Spring 3.0.3. Today, I've checked performance of my application and saw that in some operations updating of Lucene index spend minute, while Hibernate queries and transaction management with Spring take less when second. What can be the reson of such slow work of Lucene?

Hi,

unfortunately you are not giving a lot of information so I will try to give you some general hints.
Have you turned on debug log? Is there anything there? Any exceptions?
Are you using @IndexedEmbedded? If so are you sure that you don't have a cyclic object graph? Do you try to index large collections? If so, have you optimized the Hibernate mapping? This includes lazy loading options as well as a properly configured second level cache.

Also have a look at the different performance options you can use for indexing. You can set Lucene related indexing parameters like max_buffered_docs via the Hibernate configuration file. And of course there is index optimization? If you don't specify any of the automatic index optimization parameters, automatic optimization won't occur and you have to optimize manually.

I hope you got some pointers.
