I'm looking for some tips / suggestions around reducing the query time for Solr after I've post'ed a commit request. My Lucene index contains around 2,000,000 documents, and I have a job that periodically removes artibrary documents from Lucene and replaces them with fresh copies from a database. Whenever that cycle occurs, I send a commit to Solr to expose the updates. The problem is that immediately after the commit, a Solr query that previously took 5-20ms now takes 20-25 seconds. Ouch.
If this is a normal query (no faceting) then most likely the time is spent populating a lucene FieldCache entry used for sorting results. Put a static warming entry in solrconfig.xml that queries for a small number of documents and sorts that query by all the fields you commonly sort by. -Yonik
