It's important to compare apples to apples (or in this case, my macbook 
to my macbook, and doing similar functions) when showing raw numbers, 
but I haven't thought about performance for jsoniopipe since that talk 
really ;)

I assume it would not be much more difficult to match or possibly exceed 
asdf's speed, it seems we have similar design goals. I'll have to at 
some point build asdf and run some benchmarks to see what my targets 
should be. At the time I used rapidjson, I got jsoniopipe to be 
comparable with not much effort.
