I'm having trouble getting Solr to use more than one thread during index
optimizations. I have the following in my solrconfig.xml:
<mergeScheduler class="org.apache.lucene.index.ConcurrentMergeScheduler">
<int name="maxThreadCount">6</int>
</mergeScheduler>
I had the same problem some time ago, but upgrading to Solr 1.4 solved the
problem. Now it's happening again, with Solr 1.4. No matter what I set in the
maxThreadCount, I only see one thread performing the merge when I profile the
application.
Any idea what could be wrong?
Here are the details on my Solr deployment:
Solr Specification Version: 1.4.0.2009.10.14.08.05.59
Solr Implementation Version: nightly exported - yonik - 2009-10-14 08:05:59
Lucene Specification Version: 2.9.1-dev
Lucene Implementation Version: 2.9.1-dev 824988 - 2009-10-13 21:47:13
Thanks,
Gio.
