Robert Muir commented on LUCENE-1796:
-------------------------------------

unrelated to TokenStream init, but what appears to be creating additional 
slowdown is this:
{noformat}
TRACE 300197:
        
org.apache.lucene.util.AttributeSource.getAttributeImplsIterator(AttributeSource.java:140)
        
org.apache.lucene.util.AttributeSource.clearAttributes(AttributeSource.java:233)
        
org.apache.lucene.analysis.CharTokenizer.incrementToken(CharTokenizer.java:56)
        
org.apache.lucene.index.DocInverterPerField.processFields(DocInverterPerField.java:189)
{noformat}

even with reusableTokenStreams, I am still seeing a slowdown and with fairly 
granular profiling, this is consistently at the top.
is there a way to optimize clear() in any way?
