Hy all,
I'm trying to do some fine-tuning in a big application which uses Jackrabbit
2.14.1.
For bundleCacheSize, I've enabled org.apache.jackrabbit.core.persistence.bundle
log and I've done many tries untill I found the best hit/miss ratio.
Now, what I'm not understanding is:
1) How to measure the cacheSize of SearchIndex
2) Why the default value is only 1000 ? I'm currently trying with 1 milion
3) If there is a link between the bundleCache size and the SearchIndex cache
size
My configuration is the following:
<PersistenceManager
class="org.apache.jackrabbit.core.persistence.pool.OraclePersistenceManager">
<param name="bundleCacheSize" value="512"/>
<param name="consistencyCheck" value="false"/>
<param name="minBlobSize" value="16384"/>
</PersistenceManager>
<SearchIndex class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
<param name="path" value="${wsp.home}/index"/>
<!-- The number of results the query handler should initially fetch
when a query is executed. Default value: Integer.MAX_VALUE (-> all) -->
<param name="resultFetchSize" value="100" />
<param name="maxExtractLength" value="2147483647"/>
<!-- Size of the document number cache. This cache maps uuids to lucene
document numbers -->
<param name="cacheSize" value="1000000" />
<!-- With the default value of true the hierarchy cache is initialized
on startup and control is only given back when the initialization has
completed. When set to false the cache is populated during regular use. -->
<param name="initializeHierarchyCache" value="false" />
</SearchIndex>
At last, I had some difficulties finding answers in the documentation, please
could you point me to the best articles explaining these concepts?
Thanks all, best regards
