When you remove fields from your schema, you can continue to use Solr
with no problems even without a reindex.  But you won't see any benefit
to your query performance until you DO reindex.  Until the reindex is
done (ideally wiping the index first), all the data from the removed
fields will remain in the index and affect your query speeds.

Will an optimize remove those fields and corresponding data?
