Delete by query or Id very slow

[Ravi Kiran]

Hello,

             Iam using solr 1.4.1 when I delete by query or Id from solrj it
is very very slow almost like a hang. The core form which Iam deleting has
close to 850K documents in the index. In the solrconfig.xml autocommit is
set as follows. Any idea how to speed up the deletion process. Please let me
know if any more info is required



  <updateHandler class=*"solr.DirectUpdateHandler2"*>

    <!-- Perform a <commit/> automatically under certain conditions:

         maxDocs - number of updates since last commit is greater than this

         maxTime - oldest *uncommited* update (in *ms*) is this long ago
-->

    <autoCommit>

      <maxDocs>100</maxDocs>

      <maxTime>120000</maxTime>

    </autoCommit>

  </updateHandler>



Thanks,
