Hi all,
I am using Jackrabbit v1.3 and I got the performance issue.
The problem is when I visit object notes (for example, "Company"), it
costs more than 25 second to visit all "Company" notes.
The persistence manager is Oracle DB:
<PersistenceManager
class="org.apache.jackrabbit.core.state.db.OraclePersistenceManager">
The web container is Tomcat v5.5.15.
For the performance test, I list the following facts:
1.
1. In my repository, there are 339 "Company" object instances, which are
organized as a notes under "/root/repo/company-note/". Each field of
"Company" is stored as property or child note.
2. When export data from "/root/repo/company-note/", I got the XML
output of "Company" with the size of 1513KB.
3. When I export data from "/", I got the XML of 111,674 KB (I think
that all data in my repository)
4. The "Company" note is "mix:referenceable".
The CacheManager always do "resize", when I am doing "search" or any
other operation.
The console output is the following:
..
177888 [http-8080-Processor18] INFO
org.apache.jackrabbit.core.state.CacheManager - resizeAll size=8
178917 [http-8080-Processor18] INFO
org.apache.jackrabbit.core.state.CacheManager - resizeAll size=8
179947 [http-8080-Processor18] INFO
org.apache.jackrabbit.core.state.CacheManager - resizeAll size=8
180961 [http-8080-Processor18] INFO
org.apache.jackrabbit.core.state.CacheManager - resizeAll size=10
...
The configuration in repository.xml is using default values as the
following:
< <param name="useCompoundFile" value="true" />
<param name="minMergeDocs" value="100" />
<param name="volatileIdleTime" value="3" />
<param name="maxMergeDocs" value="100000" />
<param name="mergeFactor" value="10" />
<param name="bufferSize" value="10" />
<param name="cacheSize" value="1000" />
<param name="forceConsistencyCheck" value="false" />
<param name="autoRepair" value="true" />
<param name="analyzer"
value="org.apache.lucene.analysis.standard.StandardAnalyzer" />
<param name="queryClass"
value="org.apache.jackrabbit.core.query.QueryImpl" />
<param name="idleTime" value="-1" />
This performance issue is critical for me. However, I did not see other
people report the performance issue like this. I am wondering what's
wrong with my configuration.
Thanks,
