  1. Do warmup 10 seconds for JIT

  1. Update benchmark suite

    Measure elapsed time at inside of execute()
    Split without array size
    committed Mar 29, 2012
  2. Add RBTree#empty? to avoid EMPTY reference

    It needs for delete anyway (see lib/red_black_tree.rb in avl_tree gem.)
    and it avoids indirect indy binding with the current JRuby.

  1. Perf optimization for the tiny benchmark suite

    Use IO#gets instead of File#each_line to get the method linked directly.
    IO#gets is already optimized about frame handling so indy can link
    directly.

  2. Add sample input (10000 rows)

    jruby -Ilib bench/bench.rb resource/010000.csv
    committed Mar 28, 2012
  3. Update benchmark script

    committed Mar 28, 2012
  4. Adopt Left leaning RBTree

    I was unaware that LL RBTree is faster in addition to it's simpler.  See
    more detail at http://www.cs.princeton.edu/~rs/talks/LLRB/LLRB.pdf
    Trees are rebalanced in 'left leaning' manner after insert so you don't
    see '-' as results of dump_sexp (See updated test expectations.)
    
    Thanks Gaku Nakamura-san for letting me know this by implementing Scala
    version of RBTreeMap!

  1. Update benchmark script

    Show elapsed time of the last execution.
    committed Mar 27, 2012
  2. Make :color=, :right= and :left= be public

    Who can understand 'protected methods' of Ruby in 5 minutes? :)
    committed Mar 27, 2012
  3. Make EmptyTree as a subclass of RBTree

    Reduce method definition duplication.  It improves the performance in
    addition to simplify the code for explanation.
    committed Mar 27, 2012
  4. Do loop for retrieval

    No need to do recursive call.  Perf becomes slightly better.
    committed Mar 27, 2012
  5. Make rebalance code simpler

    For perf and readability.  Introduced RBTree#need_rebalance? and removed
    unnecesarry conditions to be checked for rebalance after insert.

  1. Add RBTreeMap#dump_* for debugging

  1. Test update for taking coverage

    committed Mar 23, 2012
  2. Remove unused methods (delete, etc.)

    Not needed for this benchmark.  Use avl_tree instead for actual
    Red-black tree implementation.
    committed Mar 23, 2012
  3. Revert the change to height definition

    Also, remove height() health check from regulation.

  1. Merge RBTreeHash into RBTreeMap

    extract required impl only
    committed Mar 19, 2012
  2. Make put()'s return value undefined

    As the result of discussion in ML.  No need to care for benchmarking.
    Also fixed the bug in height definition.  Height of empty list is 1, not
    0.
