I'm reading this, really great :) > Also I'd like to share some performance measurements: > HARMONY-5265 gives 4%-9% boost for SPECjbb2005.

Though I dont know how much will java6 TreeMap will gain from this(because of the complex structure), at least, the new idea(downgrade treemap to sorted array) open a new way to improve TreeMap and other similar collection utility classes. > Also I have a bunch of numbers for different micro-benchmarks and I am > planning to process and share them next week. > > > On 12/5/07, Sergey Kuksenko <[EMAIL PROTECTED]> wrote: > > > > FYI: > > I've alredy fixed some regressions and I am working on all others. > > > > > > On 12/5/07, Tim Ellison <[EMAIL PROTECTED]> wrote: > > > > > > Sergey Kuksenko wrote: > > > > I will provide real performance numbers next week.
