Hi Alan, Can you point us to the benchmarks that were created? I look back at the archive which mentions some benchmark but the sources doesn't look like they have been made available on OpenJDK - are they available somewhere else?

We should also go back through the archives for all the other benchmarks that were created in the move to the dual pivot implementation. -Alan
