It's strange that on your machine there is no difference.

Idea was to exploit new garbage collector. More specifically,
it's performance in registering new objects. Which gives
two-fold performance drop on my machine. It looks like
on your machine new collector works just same (or disabled
in both cases). I have no ideas to explain this.

I have 16 GB ram on the computer.  Could that explain anything? I'll try it again on FreeBSD if my "Attention Deficit Disorder" doesn't distract me tonight (I get about 1.5 - 2 hours at night, it's hard to stay focused on anything).  I see there is possible DTrace support for Lua via this er.. add in.. https://github.com/chrisa/lua-usdt. That would be a fun little project as I've been looking for a reason to do some more DTrace scripting.
