Normally I'd bug you about using vanilla upstream, but in this case I 
think JK's branch is in better shape.  (Apologies about not merging it 
yet, but we have a QA project we'll be testing it with and open sourcing 
soon - compiler agnostic fwiw)

Specifically about your question - It's probably unexpected and I'm 
curious what processor and version of FBSD this is.

Am I reading the result correctly that we're faster?  You may also want 
to add/test -ipa to your flags..

Side notes :
     1) -ipa == LTO in gcc which I don't know if it works at all on FBSD 
(We have some linker work that may help this situation in the future)
     2) I don't care what others say - Graphite isn't afaik production 
ready so *if* you ever do see any performance gains from it - ensure 
that you strongly validate before using in production setup
     3) We've added the latest User Guide online -

Thanks a lot for testing!
