The main reason is that I didn't want to mention all copyright and license
issues here. It's GPL licensed code, and db4objects owns the copyright. I
don't think everyone here is allowed to read GPL code at will.

The code on the blog entry is indeed slower on Harmony. Harmony is young,
and moving fast. Do we need to hide problem if there's a problem? I think
the archive of this mailing list can be also searched by many search
engines. Shall we also forbid to use any 'bad' words here?

But if you think the blog entry is not objective, it's another story. The
code in the blog is indeed slower and it's deterministic.
