great thanks. Hmm when I ran the test json I got a 212MB json 
file which the tests used. So  although the std.json takes around 
10 seconds to parse this - I can probably live with that and 
spend my energy getting on with my project. Of course it would 
have been nice to see the performance of std.json closer to that 
of rust and go instead of closer to ruby.
