Specifically, on this web page:
http://www.sai.msu.su/~megera/wiki/2009-04-03
There is a section that begins with this line of text:
Repeat test with 100,000 identical records varying array length (len).
That test shows rbtree being a third slower than HEAD. But there's
not enough information on that web page to replicate that test, so
it's hard to speculate on what may be going wrong. I don't think we
should commit this until we understand that.
