I profiled the code, and my results are very similar to yours.  My
interpretation of the results is that decoding strings that we receive
from the jansson library takes less than 10% of the CPU time.  So I
think we don't need to worry about this aspect when considering
parsing of JSON objects.

I think we can close this bug now.

Thanks.
