Thanks for taking the time to build a credibla baseline. A lot of this
depends on the perspective. We're looking at a 2.9x slowdown after all.
Right, but this isn't a 2.9x slowdown in real world code. It's a 2.9x slowdown
in
a synthetic benchmark that does nothing but increment and decrement reference
counts. Real world code would likely have a loop body and stuff. That's why I
consider it minor.
I think the cost is close to the real cost of copying a refcounted
object. Experience with refcounted languages has shown that copies do
impact the bottom line considerably. I wouldn't haste to discount a 2.9x
factor.
