In the Wiki page : http://wiki.apache.org/lucene-java/ImproveSearchingSpeed, I've found -Open the IndexReader with readOnly=true. This makes a big difference when multiple threads are sharing the same reader, as it removes certain sources of thread contention.

How to open the IndexReader with readOnly=true ?
I can't find anything related to this parameter.

Do the VJM parameters -Dslave=disabled or -Dmaster=disabled have any incidence on solr with a standart solrConfig.xml?

Thank you for your answers.

Patrick.
