What concerns me isn't the absolute number, but the differential.
Comparing how fast your machine runs to how fast mine runs doesn't tell
us much, really. How fast does Orion run HelloWorld on your machine?

Well, I was wrong there - it does correctly optimize calls.

Which would still be over 8 times longer than orion.

Bad environment would handicap Orion as well (although it may be that it
would be handicapped differently.
