Uwe Schindler commented on LUCENE-1796:
---------------------------------------

Mark: The only hotspot could be initTokenWrapper(), which does some checks, but 
normally shortcuts in filters to the input TokenStream's TokenWrapper instance.

Using incrementToken() would not help here, only if you switch of using the old 
API complete using TokenStream.setOnlyUseNewAPI(true), which can only be done 
globally, so all Solr TokenStreams must implement incrementToken().
