Johan Kindgren commented on LUCENE-1260:
----------------------------------------
Regarding the performance of the TermScorer, there could be two things to
handle to ensure that the Jvm will inline the code:
1. In the Scorer base-class, make the field 'similarity' final. (Shouldn't be
any problem since it's imutable?)
2. In the Similarity, make the internal decoder array final. That's really up
to the implementor, but the default implementations should perhaps use a final
field. Also add a note in the javadoc of this?
Would you like me to create another patch with the above changes? Maybe there
could other optimizations, haven't really looked at optimizing the code yet.
