That's quite impressive. I'd be curious to see a heat map showing where 
the time is spent. I was expecting most of the time being spent in 
running subprocesses (the actual commands), rather than within b2 
itself. So an overall performance improvement of 11% based on work on b2 
itself suggests that assumption is wrong.

Thanks,

Stefan
