I'm no Python expert, but I think that the difference is much more
likely due to which JSON processor is being used.  I suspect your Perl
environment has the JSON::XS module, which is written in C, is fast,
and is automatically invoked (if present) by "use JSON;".

In contrast, I believe that the Python "json" library is written in
Python itself.  I tried swapping in cjson and UltraJSON [1] in place
of "json" in your Python script, and in both cases it ran rather
faster.
