Commit too slow?

[LOPEZ-CORTES Mariano-ext]

Hi

After having injecting 2000000 documents in our Solr server, the commit 
operation at the end of the process (using ConcurrentUpdateSolrClient) take 10 
minutes. It's too slow?

Our auto-commit policy is the following:

                 <autoCommit>
                          <maxTime>15000</maxTime>
                          <openSearcher>false</openSearcher>
                 </autoCommit>
                 <autoSoftCommit>
                          <maxTime>15000</maxTime>
                 </autoSoftCommit>
Thanks !
