Subject Concurrent Merge Scheduler & MaxThread Count
Date Thu, 03 Dec 2009 17:30:57 GMT
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>

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:
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
